Available in PDF, EPUB and Kindle. Book excerpt: The production smoothing model of inventory behavior has a long and venerable history, and theoretical foundations which seem very strong. Yet certain overwhelming facts seem not only to defy explanation within the production smoothing framework, but actually to argue that the basic idea of production smoothing is all wrong. Most prominent wnong these is the fact that the variance of detrended production exceeds the variance of detrended sales. This paper first documents the stylized facts. Then it derives the production smoothing model rigorously and explains how the model can be amended to make it consistent with the facts. Next, estimates of stock adjustment equations derived from the theory are presented and evaluated. Finally, it reviews the theoretical and empirical evidence and tries to drawsome tentative conclusions.

Available in PDF, EPUB and Kindle. Book excerpt: A great deal of research on the empirical behavior of inventories examines some variant of the production smoothing model of finished goods inventories. The overall assessment of this model that exists in the literature is quite negative: there is little evidence that manufacturers hold inventories of finished goods in order to smooth production patterns. This paper examines whether this negative assessment of the model is due to one or both of two features: costs shocks and seasonal fluctuations. The reason for considering costs shocks is that if firms are buffeted more by cost shocks than demand shocks, production should optimally be more variable than sales. The reasons for considering seasonal fluctuations are that seasonal fluctuations account for a major portion of the variance in production and sales, that seasonal fluctuations are precisely the kinds of fluctuations that producers should most easily smooth, and that seasonally adjusted data is likely to produce spurious rejections of the production smoothing model even when it is correct. We integrate cost shocks and seasonal fluctuations into the analysis of the production smoothing model in three steps. First, we present a general production smoothing model of inventory investment that is consistent with both seasonal and non-seasonal fluctuations in production, sales, and inventories. The model allows for both observable and unobservable changes in marginal costs. Second, we estimate this model using both seasonally adjusted and seasonally unadjusted data plus seasonal dummies. The goal here is to determine whether the incorrect use of seasonally adjusted data has been responsible for the rejections of the production smoothing model reported in previous studies. The third part of our approach is to explicitly examine the seasonal movements in the data. We test whether the residual from an Euler equation is uncorrelated with the seasonal component of contemporaneous sales. Even if unobservable seasonal cost shocks make the seasonal v.

Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we present estimates of inventory models based on firm level panel data and investigate whether an over-simplified specification of the production technology may account for the failure to find technological incentives to smooth production in the context of the standard linear-quadratic model of inventory behavior. In particular, we argue that if the role of quasi-fixed factors is not modelled properly, this may lead to inconsistent estimates of marginal costs and, therefore, to erroneous conclusions about the convexity/concavity of the cost function. The model is accordingly extended to allow for a general restricted quadratic cost function, on the assumption that capital is costly to adjust. The evidence obtained by estimating the standard inventory model on a panel of Italian manufacturing firms suggests that marginal costs are decreasing. This result is overturned when one allows for the general quadratic cost function with capital as a quasi-fixed input, however, implying that the firm's technology provides incentives to smooth production. The conclusion that the cost function is convex in output is robust to allowing for adjustment costs for both capital and labor.

Available in PDF, EPUB and Kindle. Book excerpt: Monthly data in physical units for seven industries are used to examine the production smoothing hypothesis. The results strongly support this hypothesis. Significant effects of expected future sales on current production are found for four industries, and the estimated decision equations for all seven industries imply production smoothing behavior. The previous negative results regarding the hypothesis appear to be due to the use of poor data, particularly the shipments and inventory data of the Department of Commerce.

Available in PDF, EPUB and Kindle. Book excerpt: If stock-outs are ignored and if demand shocks are additive, then optimal behavior requires that the marginal cost of production (MC) be equated with the expected marginal revenue of increasing expected sales by one unit (EMR). However, with more general demand shocks (and still ignoring stock-outs), the excess of MC over EMP has the same signas the covariance of the slope of the demand curve and the marginal valuation of inventory. The equality of EMR and MC is also broken by taking account of stock-outs, even if demand shocks are additive. If there is a production lag, then taking account of stock-outs implies that optimal behavior will be characterized by production smoothing even if the cost of production is linear. Two alternative definitions of production smoothing are presented and optimal behavior in the presence of stock-outs displays each type of smoothing

This book was released on 1988 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production smoothing model of inventories has long been the basic paradigm within which empirical research on inventories has been conducted The basic hypothesis embedded In this model IS that inventories of finished goods serve primarily to smooth production levels in the face of fluctuating demand and convex cost functions. However once we allow for shocks to technology and the costs of producing output firms will also use inventories to shift production from periods in which production costs are relatively high to periods in which production costs are relatively low. In this sense inventories can serve to smooth production costs rather production levels. In this paper we examine the empirical plausibility of the production level and production cost smoothing models of inventories. Our basic strategy is to derive and contrast a set of unconditional moment restrictions Implied by these models in a way that minimizes the role of auxiliary assumptions regarding market structure and Industry demand. We find overwhelming evidence against the production level smoothing model and very little evidence against the production cost smoothing mode1 We conclude that the variance of production exceeds the variance of sales in most manufacturing industries because the production cost smoothing role of inventories is quantitatively more important than the production level smoothing role of inventories.

Book excerpt: Research in macroeconomics in the last thirty years has featured, almost exclusively on two characteristics: an emphasis on the microfoundations of macroeconomics and secondly, intertemporal economics, that is, the behavior of economic actors over time. Curiously, textbooks in intermediate macroeconomics have been very slow to adopt these traits. The aim of this book is to bring intermediate instruction in macroeconomics fully into line with the direction taken by the research community. Key hallmarks of the text include: a full introduction to the microfoundations of consumption and investment a complete model of the labor market with profit maximization for firms to determine labor demand and a utility maximization model to determine labor supply an analysis of the Baumol-Tobin model to determine money demand accompanied by a discussion of traditional money supply Possessing a full range of additional learning features including a companion website, test bank and instructor’s manual, the book takes an international view of macroeconomics with case studies and examples from the United States and beyond.

This book was released on 2012-12-06 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an econometric modeling approach for analysing macroeconomic disequilibria, focusing on the market for goods and labor and the spillovers between these markets transmitted through firms' decisions in the production sphere. The macroeconomic markets are treated as heterogeneous aggregates, consisting of a multitute of micro markets on which demand/supply ratios differ. Disequilibrium models have been under attack because they neglect that inventories enable firms to smooth production over the cycle, but the author argues that buffer stocks (output inventories, unfilled orders) should be accounted for within the disequilibrium framework, giving rise to a dynamic modification rather than a fundamental invalidation of rationing and spillover effects. The model developed in this book combines traditional Keynesian-type analysis with supply-side considerations and at the same time allows for micro-level imbalance. The resulting econometric structure is inherently nonlinear, reflecting that the response of economic activity to demand-side and supply-side factors varies over the cycle, depending on the aggregate mix of regimes. The model is estimated with quarterly data for Switzerland. Various simulation experiments clearly demonstrate the potential of this type of model for empirical business cycle analysis and policy discussions.
