Book excerpt: Standard macro models typically assume that producers sell goods directly to final consumers, while, in reality, the distribution network or vertical structure from a manufacturer to a consumer takes various forms. The boundary of firms, or to what extent a firm wishes to extend its distribution or manufacturing process is not a trivial issue when firms develop sourcing strategies. A substantial number of recent studies in international trade have demonstrated systematic patterns in intra-firm trade patterns and price patterns. Inclusion of vertical chains possibly generates frictions by means of double-marginalization problem, asymmetric information and coordination issues, while the choice of vertical structure is an endogenous choice of transaction cost minimization and contractibility. The first part of work discusses the price patterns by documenting several facts about price rigidity using a large grocery retail data set. The role of retailers has been completely neglected in standard macro pricing models. However, consumers seldom interact with manufacturers directly, especially for grocery items. The assumption that retail level is negligible would be innocuous only if the wholesale price dynamics is similar to retail price dynamics. That is, only when retailers fully pass through the wholesale price to consumers and do not influence the prices that have been set by manufacturers would this assumption make sense. Using detailed information of weekly price and cost from a major retailer store that operates across the United States, we find strong evidence that retail price dynamics are completely different from manufacturer price dynamics. We find two main reasons for why retail prices cannot fully reflect wholesale prices. First, retailers cannot do so because retailers face costs of their own aside from wholesale price. Second, retailers react to variations in demand more directly than wholesalers. Pass-through rate of retailer cost (including wholesale price and extra costs to retailers) to retail price is incomplete. We also find that (1) retail pass-through rate is incomplete, (2) retail pass-through rate and retail price rigidity is negatively correlated, (3) categories with higher retail mark-up show lower pass-through rate, (4) price rigidity is heterogeneous across categories, (5) competition within a category shows positive correlation with pass-through rate, but the correlation is less obvious in the scatter plots and (6) retail price duration is shorter than wholesale price duration, while retail price duration is longer than retail cost duration. In a simple model where retailers play non-neutral role, we can successfully explain the empirical findings, while models with neutral retailers or no retailers fail to explain the findings. The second part of work discusses the relationship between the vertical structure and the price rigidity. In the job market paper, "Vertical Integration and Retail Pricing Facts for Macroeconomists: Private Label vs. National Brand" (co-authored with Nicholas Li), we propose to extend this analysis to retail behavior and also into closed economy using a data set that contains prices and wholesale costs for a retail chain that operates in the United States. The retailer owns numerous brands that are sold in its stores - ownership in this case implies control over branding, marketing and packaging in all cases and in many cases control over manufacturing as well. We call these private labels and consider equivalent to intra-firm in open macro literature. Beyond generalizing the findings of previous studies to the retail sector and a different data set, the significant growth of store-brands makes the impact of vertical integration in retail on intra and inter-national pricing behavior of independent interest. By analyzing the main dimensions of pricing (duration, cost pass-through and synchronization), we find that the private label goods show shorter price duration, greater cost shock pass-through and greater synchronization of price changes than national brands counterpart. These findings are consistent with previous literature using trade dataset. We compare two existing models that can potentially explain these facts -one featuring symmetric retail demand but different vertical structures/double-marginalization, and the other featuring demand asymmetry and price discrimination as a motive for sales to find evidence that two models are complementary. If vertical structure is endogenous, with vertically integrated lower-priced products gaining market share for product categories, we argue that it can serve as a potential multiplier for demand-based induced changes in retail pricing behavior. One example that shows retailers' non-neutral role in price-setting mechanism is the existence of sales at retail level. With a recent surge of micro-level data sets from various sources, researchers have been able to examine price dynamics at a disaggregate level and to test previously established macro-pricing models. A notable feature of price dynamics across all of these data sets is significant heterogeneity across products and sectors in measured pass-through and frequency due to temporary discounts, or sales. Previous studies have demonstrated that the retailer is largely responsible for the timing and size of temporary discounts. Sales prices behave qualitative and quantitatively different from regular prices. Yet, researchers have not reached a conclusion whether or not and how to incorporate intermittent price into crucial issues, such as, macro price-setting models and price index constructions. The core of the question is whether sales have any implications for business cycle and monetary neutrality. The question is also intimately related to how economic agents respond to shocks - how retailers adjust their profit-maximizing strategies, how consumers adjust their consumption patterns in response to cost shocks. The third chapter of work, "On the Cyclicality of Effective Prices" with Professors Yuriy Gorodnichenko and Olivier Coibin directly tackles this issue. We study the cyclical properties of sales, regular price changes and average prices paid by consumers in a dataset containing prices and quantities sold for numerous retailers across a variety of U.S. metropolitan areas. Both the frequency and size of sales fall when unemployment rates rise and yet the inflation rate of average prices paid by consumers declines with higher unemployment. This discrepancy can be reconciled by consumers reallocating their expenditures across retailers, a feature of the data which we document and quantify. The results point toward a cyclical mis-measurement of inflation which can account for part of the "missing disinflation" during the Great Recession.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation examines three important issues in energy markets: price dynamics, information flow, and structural change. We discuss each issue in detail, building empirical time series models, analyzing the results, and interpreting the findings. First, we examine the contemporaneous interdependencies and information flows among crude oil, natural gas, and electricity prices in the United States (US) through the multivariate generalized autoregressive conditional heteroscedasticity (MGARCH) model, Directed Acyclic Graph (DAG) for contemporaneous causal structures and Bernanke factorization for price dynamic processes. Test results show that the DAG from residuals of out-of-sample-forecast is consistent with the DAG from residuals of within-sample-fit. The result supports innovation accounting analysis based on DAGs using residuals of out-of-sample-forecast. Second, we look at the effects of the federal fund rate and/or WTI crude oil price shock on US macroeconomic and financial indicators by using a Factor Augmented Vector Autoregression (FAVAR) model and a graphical model without any deductive assumption. The results show that, in contemporaneous time, the federal fund rate shock is exogenous as the identifying assumption in the Vector Autoregression (VAR) framework of the monetary shock transmission mechanism, whereas the WTI crude oil price return is not exogenous. Third, we examine price dynamics and contemporaneous causality among the price returns of WTI crude oil, gasoline, corn, and the S&P 500. We look for structural break points and then build an econometric model to find the consistent sub-periods having stable parameters in a given VAR framework and to explain recent movements and interdependency among returns. We found strong evidence of two structural breaks and contemporaneous causal relationships among the residuals, but also significant differences between contemporaneous causal structures for each sub-period.

Available in PDF, EPUB and Kindle. Book excerpt: This paper analyzes and characterizes the dynamics of wealth-share and equilibrium price in a stochastic general equilibrium model with heterogeneous consumers. The characterization enables a comparison between probabilistic learning and price evolution, revealing that prices incorporate "sparse" information efficiently. Results on wealth-share are obtained by comparing traders' optimal investment-consumption plans against their prices. This novel approach extends recent results in the literature by providing a condition that is necessary as well as sufficient for a trader to vanish. The results are applied to survival in iid, survival in large economies, and survival of traders that follow strategies commonly observed in real markets.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This dissertation develops three essays on dynamic pricing to investigate two important topics in industrial organization: price dispersion and price discrimination. The first essay considers a stylized model of dynamic price competition in which each seller sells one unit of a homogeneous commodity by posting prices in every period to maximize the expected profits with discounting. A random number of buyers come to the market in each period. Each buyer demands at most one unit of the good, and they all have a common reservation price. They know all prices posted by all firms in the market; hence search is costless. I show that when there is a positive probability of excess demand, the model has a unique (symmetric) mixed-strategy equilibrium. In this equilibrium, each seller posts a price in every period according to a non-degenerate distribution, which is determined by the number of sellers remaining in the market in that period. Sellers play mixed strategies as they are indifferent between selling sooner at a lower price and waiting to sell at a higher price later. Thus, price dispersion not only exists in every period among firms, but also persists over time. In the second essay, I consider a monopolist who can sell vertically differentiated products over two periods to heterogeneous consumers. Consumers each demand one unit of the product in each period. In the second period, consumers are sorted into different segments according to their first-period choice, and the monopolist can offer different menus of contracts to different segments. In this way, the monopolist can price discriminate consumers not only by product quality, but also by purchase history. I fully characterize the monopolist's optimal pricing strategy when the type space is discrete and a simple condition is given to determine whether the monopolist should price discriminate consumers by product quality in the first period. When the consumers' type space is a continuum, I show that there is no fully separating equilibrium, and some properties of the optimal menu of contracts (price-quality pairs) are characterized within the class of partition PBE (Perfect Bayesian Equilibrium). The monopolist will offer only one quality in the first period when the social surplus function is log submodular or the firm and consumers are patient. If it is optimal for the firm to offer only one quality in the first period, the optimal market coverage in the first period is smaller than that in the static model. Furthermore, in equilibrium there are some high-type consumers choosing to downgrade the product in the second period, a phenomenon that has never been addressed in the literature. In the second essay, when the consumers' type space is a continuum, the analysis of the optimal menu of contracts is restricted within the class of partition PBE. The third essay provides a justification for this qualification. I ask whether an optimal menu of contracts can induce a non-partition continuation equilibrium by scrutinizing the example constructed by Laffont and Tirole (1988). They construct a non-partition continuation equilibrium for a given first-period menu of incentive contracts and conjecture that this continuation equilibrium need not be suboptimal for the whole game under small uncertainty. I construct two first-period incentive schemes leading to a partition continuation equilibrium and show that, regardless of the extent of uncertainty, their non-partition continuation equilibrium generates a smaller payoff than one of two partition continuation equilibria for the principal. In this sense, Laffont and Tirole's menu of contracts, giving rise to a non-partition continuation equilibrium, is not optimal. I provide an intuition behind this result, hoping to shed light on the problem of dynamic contracting without commitment.

Download or read book Three Essays In Commodity Price Dynamics written by Amal Dabbous and published by . This book was released on 2015 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis consists of three essays in commodity price dynamics. In the first essay, we embed a staggered price feature into the speculative storage model of Deaton and Laroque (1996). Intermediate goods inventory speculators are added as an additional source of intertemporal linkage which helps us to replicate the stylized facts of the observed commodity price dynamics. The staggered pricing mechanism adopted in this paper can be viewed as a parsimonious way of approximating various types of frictions that increase the degree of persistence in the first two conditional moments of commodity prices. The structural parameters of our model are estimated by simulated method of moments using actual prices for four agricultural commodities. Simulated data are then employed to assess the effects of our staggered price approach on the time series properties of commodity prices. Our results lend empirical support to the possibility of staggered prices. The second essay investigates the determinants of the percentage change in commodity prices. We apply the dynamic Gordon growth model technique and conduct the variance decomposition for the percentage change in spot commodity prices to 6 agricultural commodities. The model explains the percentage change in spot commodity prices in terms of the expected present discounted values of interest rate, yield spread, open interest and convenience yield. Empirical results indicate that the model is successful in capturing a large proportion of the variability in the 6 agricultural commodity prices. Moreover, we show that yield spread and open interest help predicting changes in commodity prices. Finally, the third essay evaluates different hedging strategies for eleven commodities. In addition to the traditional regression hedge ratio model (OLS) and the vector error correction model (VECM), we estimate dynamic hedge ratios using the conventional dynamic conditional correlation model (DCC) of Engle (2002) and the diagonal BEKK model (DBEKK) of Engle and Kroner (1995). Moreover, we propose two more advanced models, the DCC model and the DBEKK model that will account for the impact of the growth rate of open interest on market’s volatility and co-movements of commodity spot and futures returns. The empirical analysis shows that adding the growth rate of open interest improves the in-sample hedging effectiveness of the DCC model. Furthermore, the out-of-sample hedging exercise empirical results show that static models present the best out-of-sample hedging performance for 5 of the commodities. The DCC model presents the smallest basis variance for 4 of the commodities. The DBEKK model with the growth rate of open interest performs the best in terms of the basis variance reduction for corn and wheat. Our out-of-sample empirical findings provide important implications for futures hedging and highlight the fact that the use of static models to determine the optimal hedge ratio could be more effective than the use of dynamic hedge ratio models.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains essays in honour of Claus Weddepohl who, after 22 years, is retiring as professor of mathematical economics at the Department of Quantitative Economics of the University of Amsterdam. Claus Weddepohl may be viewed as th~ first Dutch mathematical economist in the general equi librium tradition of Arrow, Debreu and Hahn. The essays in this book are centered around the themes Equilibrium, Markets and Dynamics, that have been at the heart of Weddepohl's work on mathematical economics for more than three decades. The essays have been classified according to these three themes. Admittedly such a classification always is somewhat arbitrary, and most essays would in fact fit into two or even all three themes. The essays have been written by international as well as Dutch friends and colleagues including Weddepohl's former Ph. D. students. The book starts with a review of Claus Weddepohl's work by Roald Ramer, who has been working with him in Amsterdam for all those years. The review describes how Weddepohl became fascinated by general equilibrium theory in the early stages of his career, how he has been working on the theory of markets throughout his career, and how he turned to applications of nonlinear dynamics to price adjustment processes in a later stage of his career. The first part of the book, Equilibrium, collects essays with general equilib rium theory as the main theme.

Download or read book Three Essays on Retail Price Dynamics written by Andres Elberg and published by . This book was released on 2010 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three essays on the dynamics of retail prices. The first chapter uses a novel data set of weekly-sampled store-level retail prices for narrowly defined goods observed across 12 cities in Mexico to study the relative magnitude of aggregation biases in estimates of convergence to the Law of One Price (LOP). I find that temporal aggregation can severely bias estimates of persistence in relative prices. Both panel estimations of higher-order autoregressive processes and Monte Carlo experiments suggest that using quarterly aggregated data (from weekly-sampled data) can overestimate the half-life of deviations from the Law of One Price (LOP) by a factor of 4. I do not find evidence that pooling across goods with heterogeneous dynamics biases persistence estimates. The analysis also suggests that intercity prices converge rapidly to the LOP in an absolute sense (the median half-life is estimated at 3 weeks) and the existence of only a weak association between price gaps across cities and physical distance. The second chapter studies patterns of retail price adjustment at the store level using a unique scanner data set of weekly retail prices, quantities sold and wholesale costs for a cross-section of retailers in Chile. In line with evidence reported for the U.S. (Eichenbaum, Jaimovich and Rebelo, 2010; Klenow and Malin, 2010), posted prices tend to revolve around more persistent reference prices. The implied duration of reference prices is estimated at 2-3 quarters versus 3-4 weeks in the case of posted prices. I find strong evidence that reference prices respond to retailer-level shocks. Comovement in the reference price of a given barcode across retailers is found to be significantly larger for stores belonging to the same retail chain than for stores that belong to different retail chains. Furthermore, most of the variation in the frequency of reference price adjustment is explained by "chain effects". Evidence on the synchronization of price changes suggests that price changes tend to be staggered across stores belonging to different retail chains but synchronized within chains. The third chapter uses a scanner dataset including weekly prices and costs from a large retailer in Chile to study the relationship between price rigidities and intra-national deviations from the law of one price (LOP). I find that, controlling for transportation costs (proxied by distance), more flexible prices are associated with a larger volatility of deviations from the LOP. The effect is econominally non-negligible and holds for both retail- and wholesale-level prices. The distance equivalent of a 0.01 change in the frequency of retail (wholesale) price change is estimated at 370 (294) kilometers.
