This book was released on 2009 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stock prices are very volatile. Their fundamental value as measured by the ex-post realized net present value of dividends fluctuates far less than the stock price itself. A hot debate about the efficiency of stock markets has arisen from this observation. Many researchers attribute at least some of this "excess volatility" we observe in stock prices to inefficient actions of economic agents. This dissertation is about the macroeconomic consequences of excess volatility in stock prices. It demonstrates that this volatility can lead to large reductions in welfare for households and discusses ways for governmental intervention to alleviate adverse effects. The dissertation furthermore shows that large stock market volatility can arise from tiny, in fact arbitrarily small, errors in agents' actions or in their belief formation.

Available in PDF, EPUB and Kindle. Book excerpt: In the first chapter, I analyze the question that whether the elasticity of intertemporal substitution or risk aversion is more important determinant of precautionary savings. This is an important question since a significant fraction of the capital accumulation is due to precautionary savings according to studies. Thus, knowing the important determinant of precautionary savings will be helpful to understand the capital accumulation mechanism. I look into the effects of the elasticity of intertemporal substitution and risk aversion on precautionary savings separately by performing simulations in order to obtain numerical results. I find that the elasticity of intertemporal substitution is more important determinant than risk aversion. In the second chapter, I study the impact of the introduction of futures trading on the volatility of the underlying spot market for Turkish Istanbul Stock Exchange (ISE). The economic literature intensified the debate on the negative or positive impact of futures trading on the stock market volatility. Although there are empirical studies for different countries with mixed results, most of them focus on developed countries. There are a few empirical researches on emerging markets. Analyzing the data, following results are obtained for ISE. First, the results suggest that the introduction of futures trading has decreased the volatility of ISE. Second, the results show that futures trading increases the speed at which information is impounded into spot market prices. Third, the asymmetric responses of volatility to the arrival of news for ISE have increased after the introduction of futures trading. In the third chapter, I investigate the presence of calendar anomalies in ISE by using GARCH models. The presence of calendar anomalies and their persistence presence since their first discovery still remains a puzzle to be solved. On the other hand, there are some claims that general anomalies are much less pronounced after they became known to the public. Most of the studies have examined the developed financial markets. However, it is important to test the calendar effects in data sets that are different from those in which they are originally discovered and so ISE is a good case to test the calendar effects for a developing country.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three essays in macroeconomics. The first one essay discusses the reasons of Chinese huge foreign reserves holdings. It contributes to the literature of sudden stops, precautionary saving and foreign assets holdings. In the second essay, I study the price volatility of commodities and manufactured goods. I measure the price volatility of each individual goods but not on the aggregated level and therefore the results complete the related study. The third essay explores the correlation between the relative volatility of output to money stock and financial development. It extends the application of financial accelerator model. In the first essay, I address the question of China's extraordinary economic growth during the last decade and huge magnitude of foreign reserves holdings. The coexistence of fast economic growth and net capital outflow presents a puzzle to the conventional wisdom that developing countries should borrow from abroad. This paper develops a two-sector DSGE model to quantify the contribution of precautionary saving motivation against economic sudden stops. The risk of sudden stops comes from the lagged financial reforms in China, in which banks continue to support inefficient state-owned enterprises, while the more productive private firms are subject to strong discrimination in credit market, and face the endogenous collateral constraints. When the private sector is small, the impact on aggregate output of binding credit constraints is limited. However, as the output share of private sector increases, the negative effect of financial frictions on private firms grows, and it is more likely to trigger a nation-wide economic sudden stop. Thus, the precautionary savings rise and the demand for foreign assets also increases. Our calibration exercise based on Chinese macro data shows that 25 percent of foreign reserves can be accounted for by the rising probability of sudden stops. The second essay studies the relative volatility of commodity prices with a large dataset of monthly prices observed in international trade data from the United States over the period 2002 to 2011. The conventional wisdom in academia and policy circles is that primary commodity prices are more volatile than those of manufactured products, although most existing studies do not measure the relative volatility of prices of individual goods or commodities. The literature tends to focus on trends in the evolution and volatility of ratios of price indexes composed of multiple commodities and products. This approach can be misleading. The evidence presented here suggests that, on average, prices of individual primary commodities are less volatile than those of individual manufactured goods. Furthermore, robustness tests suggest that these results are not likely to be due to alternative product classification choices, differences in product exit rates, measurement errors in the trade data, or the level of aggregation of the trade data. Hence the explanation must be found in the realm of economics, rather than measurement. However, the challenges of managing terms of trade volatility in developing countries with concentrated export baskets remain. The third essay tries to understand why the relative volatility of nominal output to money stock is negatively related to countries' financial development level from cross-country evidence. In the paper I modify Bernanke et al. (1999)'s financial accelerator model by introducing the classic money demand function. The calibration to US data shows that the model is able to replicate this empirical pattern quite well. Given the same monetary shocks, countries with poorer financial system have larger output volatility due to the stronger effect of financial accelerator mechanism.

Book excerpt: This thesis contains three essays that employ macroeconomic theory to study the implications of volatility, financial frictions and reserve requirements. The first essay uses an imperfect information model where agents solve a signal extraction problem to study the effect of volatility on the economy. A real business cycle model where the agent faces imperfect information regarding productivity is used to address the question. The main finding is that the variance of the productivity process components has a small negative short run impact on the economy's real variables. However, imperfect information dampens the effects of volatility associated to permanent components of productivity and amplifies the effects of volatility associated to transitory components. The second essay presents a partial equilibrium characterization of the credit market in an economy with partial financial dollarization. Financial frictions (costly state verification and banking regulation restrictions), are introduced and their impact on lending and deposit interest rates denominated in domestic and foreign currency studied. The analysis shows that reserve requirements act as a tax that leads banks to decrease deposit rates, while the wedge between foreign and domestic currency lending rates is decreasing in exchange rate volatility and increasing in the degree of correlation between entrepreneurs' returns and the exchange rate. The third essay introduces an interbank market with two types of private banks and a central bank into a New-Keynesian DSGE model. The model is used to analyse the general equilibrium effects of changes to reserve requirements, while the central bank follows a Taylor rule to set the policy interest rate. The paper shows that changes to reserve requirements have similar effects to interest rate hikes and that both monetary policy tools can be used jointly in order to avoid big swings in the policy rate or a zero bound.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation includes two different groups of objects in macroeconomics and financial economics. In macroeconomics, the aggregate investment fluctuation and its relation to an individual firm's behavior have been extensively studied for the past three decades. Most studies on the interdependence behavior of firms' investment focus on the key issue of separating a firm's reaction to others' behavior from reaction to common shocks. However, few researchers have addressed the issue of isolating this endogenous effect from a statistical and econometrical approach. The first essay starts with a comprehensive review of the investment fluctuation and firms' interdependence behavior, followed by an econometric model of lumpy investments and an analysis of the binary choice behavior of firms' investments. The last part of the first essay investigates the unique characteristics of the Italian economy and discusses the economic policy implications of our research findings. We ask a similar question in the field of financial economics: Where does stock market volatility come from? The literature on the sources of such volatility is abundant. As a result of the availability of high-frequency financial data, attention has been increasingly directed at the modeling of intraday volatility of asset prices and returns. However, no empirical research of intraday volatility analysis has been applied at both a single stock level and industry level in the food industry. The second essay is aimed at filling this gap by modeling and testing intraday volatility of asset prices and returns. It starts with a modified High Frequency Multiplicative Components GARCH (Generalized Autoregressive Conditional Heteroscedasticity) model, which breaks daily volatility into three parts: daily volatility, deterministic intraday volatility, and stochastic intraday volatility. Then we apply this econometric model to a single firm as well as the whole food industry using the Trade and Quote Data and Center for Research in Security Prices data. This study finds that there is little connection between the intraday return and overnight return. There exists, however, strong evidence that the food recall announcements have negative impacts on asset returns of the associated publicly traded firms.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three essays that examine the role of institutional frictions and belief formation in understanding financial and macroeconomic puzzles. In two chapters, I study on the transmission channels by which institutional frictions impact aggregate business cycles. In another chapter I explore the link between belief formation and aggregate asset price dynamics. In the first chapter, I study the macroeconomic effects of a 1982 SEC rule that made share buybacks a viable alternative to dividends for paying out funds to shareholders. I propose a quantitative model of heterogeneous firms with dividend adjustment costs and a manager-shareholder conflict, matched to micro data on US corporations' cash flow statements. The flexibility of buybacks improves welfare by reducing the misallocation of capital. This is not only because investors can more easily shift resources to more productive firms, but also because stock prices become more responsive to productivity and thus help align incentives of managers and shareholders. This "stock price effect" allows the model to not only account for a decline in investment and increase in productivity, but also the increase in corporate cash holdings over the last decades. In the second chapter, co-authored with Sean Myers, we study how shareholder beliefs and firm payout decisions affect aggregate asset prices. Using survey forecasts, we find that cash flow growth expectations explain most movements in the S\& P 500 price-dividend and price-earnings ratios, accounting for at least 93\% and 63\% of their variation. These expectations comove strongly with price ratios, even when price ratios do not predict future cash flow growth. In comparison, return expectations have low volatility and small comovement with price ratios. Short-term, rather than long-term, expectations account for most price ratio variation. We propose an asset pricing model with beliefs about earnings growth reversal that accurately replicates these cash flow growth expectations and dynamics. In the third chapter, co-authored with Stephen McKnight, we study how institutional frictions in developing economies impact business cycles. This chapter investigates the role of labor informality in the propagation of transitory shocks and its implications for interest rate policy in preventing self-fulfilling inflation expectations. We develop a dynamic New Keynesian model where the size of the informal sector reacts to search and matching frictions in the formal sector, which can account for the observed behavior of formal and informal employment in Mexico. We show that informality reduces the volatility of aggregate consumption and employment, but investment volatility increases. While informality amplifies the propagation of demand shocks on inflation, it dampens the response of output, weakening the transmission mechanism of monetary policy to output. For interest-rate feedback rules that react to formal measures of inflation, we find that informality significantly restricts the ability of the Taylor principle to ensure determinacy. However, we show that determinacy can be restored when policy also responds to formal output.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three essays that explore the information content embedded in equity options. The results improve our understanding of the cross-section of option returns, informed trading in the options market, and the industry effect of IPOs. In the first essay, we study the relation between option-implied skewness (IS) and the crosssection of option returns under daily hedging to better understand skewness pricing in isolation from lower moments. Creating portfolios of delta-hedged (D-hedged) and delta-vega-hedged (DV-hedged) options with daily rebalancing, we find that IS is negatively (positively) related to call (put) option returns, but the relation to put options is statistically significant only during economic recessions. The relation is more substantial when the underlying stock has a larger market beta and when the firm has more severe information opacity. Our results suggest that investors' skewness preference grows stronger with greater market risk and lower information quality. In the second essay, we examined the informed trading in the options market before FDA drug advisory committee meetings. We find significant abnormal options trading volume before both meeting dates and report creation dates, particularly for small drug firms. Abnormal volume significantly predicts post-meeting stock returns. Informed traders prefer out-of-the-money options and choose maturities to cover the dates when reports are publicly released. They prefer to sell options close to the meeting date, perhaps to capture returns from both expected stock price changes and the sharp drop in implied volatility post-meeting. In the third essay, I investigate the effect of initial public offerings (IPOs) on industry competitors' options market. I find that rival firms' put (call) options volume increases (decreases) around IPOs, leading to price pressure on call options relative to put options as measured by the implied volatility spread. Rival firms' reaction in the options market also predicts the IPO firms' post-IPO stock performance. Lastly, rival firms with strong operating income experience less negative impact in the options market, suggesting competitive operation performance help stabilize rival firms' options market around IPOs.

Universidad de Cantabria. This book was released on 2019-02-15 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Do financial derivatives enhance or impede innovation? We aim to answer this question by examining the relationship between equity options markets and standard measures of firm innovation. Our baseline results show that firms with more options trading activity generate more patents and patent citations per dollar of R&D invested. We then investigate how more active options markets affect firms' innovation strategy. Our results suggest that firms with greater trading activity pursue a more creative, diverse and risky innovation strategy. We discuss potential underlying mechanisms and show that options appear to mitigate managerial career concerns that would induce managers to take actions that boost short-term performance measures. Finally, using several econometric specifications that try to account for the potential endogeneity of options trading, we argue that the positive effect of options trading on firm innovation is causal.

Available in PDF, EPUB and Kindle. Book excerpt: Economic growth, low inflation, and financial stability are among the most important goals of policy makers, and central banks such as the Federal Reserve are key institutions for achieving these goals. In Asset Prices and Monetary Policy, leading scholars and practitioners probe the interaction of central banks, asset markets, and the general economy to forge a new understanding of the challenges facing policy makers as they manage an increasingly complex economic system. The contributors examine how central bankers determine their policy prescriptions with reference to the fluctuating housing market, the balance of debt and credit, changing beliefs of investors, the level of commodity prices, and other factors. At a time when the public has never been more involved in stocks, retirement funds, and real estate investment, this insightful book will be useful to all those concerned with the current state of the economy.
