Book Description
We estimate a DSGE model with (S,s) inventory policies. We find that (i) taking inventories into account can significantly improve the empirical fit of DSGE models in matching the standard business-cycle moments (in addition to explaining inventory fluctuations); (ii) (S,s) inventory policies can significantly amplify aggregate output fluctuations, in contrast to the findings of the recent general-equilibrium inventory literature; and (iii) aggregate demand shocks become more important than technology shocks in explaining the business cycle once inventories are incorporated into the model. An independent contribution of our paper is that we develop a solution method for analytically solving (S,s) inventory policies in general-equilibrium models with heterogeneous ጿirms and a large aggregate state space, and we illustrate how standard log-linearization methods can be used to solve various versions of our inventory model, generate impulse response functions, and estimate the model's deep structural parameters.

Book Description
We develop an equilibrium business cycle model in which the producers of final goods pursue generalized (S,s) inventory policies with respect to intermediate goods, a consequence of nonconvex factor adjustment costs. Calibrating our model to reproduce the average inventory-to-sales ratio in postwar U.S. data, we find that it explains over half of the cyclical variability of inventory investment. Moreover, inventory accumulation is strongly procyclical, and production is more volatile than sales, as in the data. The comovement between inventory investment and final sales is often interpreted as evidence that inventories amplify aggregate fluctuations. In contrast, our model economy exhibits a business cycle similar to that of a comparable benchmark without inventories, though we do observe somewhat higher variability in employment, and lower variability in consumption and investment. Thus, equilibrium analysis, which necessarily endogenizes final sales, alters our understanding of the role of inventory accumulation for cyclical movements in GDP. The presence of inventories does not substantially raise the variability of production, because it dampens movements in final sales. Similarly, when reductions in adjustment costs lower, but do not eliminate, average inventory holdings, the variability of GDP is essentially unchanged, because the reduced costs cause an o.setting rise in the variability of final sales.

Book Description
Modern business cycle theory and growth theory uses stochastic dynamic general equilibrium models. Many mathematical tools are needed to solve these models. The book presents various methods for computing the dynamics of general equilibrium models. In part I, the representative-agent stochastic growth model is solved with the help of value function iteration, linear and linear quadratic approximation methods, parameterised expectations and projection methods. In order to apply these methods, fundamentals from numerical analysis are reviewed in detail. Part II discusses methods for solving heterogeneous-agent economies. In such economies, the distribution of the individual state variables is endogenous. This part of the book also serves as an introduction to the modern theory of distribution economics. Applications include the dynamics of the income distribution over the business cycle or the overlapping-generations model. Through an accompanying home page to this book, computer codes to all applications can be downloaded.

Book Description
This dissertation focuses on the consequences of labor market policies, environmental cap-and-trade policies, and monetary policy. These three types of economic policies are admittedly very distinct, but they are tied together by the type of analysis I employ to study these policies. For each, I develop a specific general equilibrium model aimed at highlighting the policy in question and use cutting-edge computational methods to numerically solve the model across an array of potential policies. In the first chapter, The Distributional Effects of Labor Adjustment Cost Policies, I introduce a general equilibrium model with heterogeneous plants and labor adjustment costs to explore both the aggregate and distributional effects of labor adjustment costs. I use the model to analyze the effects of policies that would repeal all or half of state-mandated firing costs in European countries. The model predicts that a full repeal of state-mandated firing costs in the average European country would increase aggregate labor productivity by 0.7%-6.2% while increasing the rate of job turnover by 65%-420%. In the second chapter, Emissions Allowance Allocation in Cap-and-Trade Policies, I present a version of "Impacts of Alternative Emissions Allowance Allocation Methods Under a Federal Cap-and-Trade Program", co-written with Lawrence H. Goulder and Michael Dworsky, published in the Journal of Environmental Economics and Management, Volume 60, Issue 3, November 2010, pages 161-181. To examine the implications of alternative allowance allocation designs for industry profits and GDP under a federal cap-and-trade program to reduce greenhouse gas emissions, we employ a general equilibrium model of the U.S. economy with a unique treatment of capital dynamics that permits close attention to profit impacts. Effects on profits depend critically on the relative reliance on auctioning or free allocation of allowances. Freely allocating fewer than 15\% of the emissions allowances generally suffices to prevent profit losses in the most vulnerable U.S. industries. Freely allocating all of the allowances substantially overcompensates these industries. When emissions allowances are auctioned and the proceeds are employed to finance cuts in income tax rates, GDP costs are about 33 percent lower than when all the allowances are freely allocated. The results are robust to policies differing in stringency, the availability of offsets, and the opportunities for intertemporal trading of allowances. In the final chapter, I present \textit{Interbank Lending and Monetary Policy in a DSGE Model}, which was written with Josephine Smith. We build a DSGE model with heterogeneous banks and interbank lending to explore how monetary policy should respond to shocks in the interbank lending market. To do this, we build upon the Bernanke, Gertler, and Gilchrist \citeyear{bgg1999} model of the financial accelerator by introducing a monopolistically competitive banking sector. The model is the first of its kind to include a monopolistically competitive banking sector, heterogeneous banks, and an interbank lending market. We find that the heterogeneous monopolistically competitive banking sector mitigates macroeconomic variance in the model relative to a perfectly competitive banking sector. Multiple banks that imperfectly compete with each other can help absorb shocks better than a single representative bank and mitigate the financial accelerator effect. We also find that financial supply side shocks, as measured by shocks to the productivity of bank loan production, have a much greater effect on the real economy than the demand-side financial shocks. In addition, we find that shocks to the ex-ante most productive banks have a larger effect on the real economy than shocks to the ex-ante least productive banks because the banks with high productivity (ex-ante) have a larger share of the financial market. Analyzing the effect of shocks to interbank lending rates (relative to the central bank policy rate), we find large macroeconomic effects of such policies. Finally, we find that a monetary policy interest rate rule that incorporates the financial sector can actually dampen the effects of traditional non-financial shocks such as productivity, government spending, and monetary policy shocks and leads to a significant decrease in business-cycle volatility.

Book Description
In Consumption Behavior and the Effects of Government Fiscal Policies, Randall Mariger explores how people make decisions about how much to consume and save over their lifetimes. An understanding of these issues illuminates not only individual behavior but important properties of the macro economy as well. The most popular framework for analyzing consumption has been the life-cycle theory. Mariger tests two fundamental, and controversial, assumptions underlying the theory--that there are no planned bequests and that human capital is marketable. To do this, he fits a structural consumption model that incorporates endogenous liquidity constraints (non-marketability of human capital), but no planned bequests, to data on a cross-section of U. S. families. This estimated model, in conjunction with estimates of alternative models, enables him to make inferences about the respective effects of liquidity constraints and social security wealth on consumption. This latter effect yields indirect evidence concerning planned bequests. Mariger also presents direct evidence concerning bequest behavior. Among his findings are that the model fits the data very well in spite of its tight theoretical structure; that liquidity constraints are prevalent and have important effects on consumption behavior; that planned bequests appear not to be common among families in the lower 99.1% of the wealth distribution; and that families in the upper 0.9% of the wealth distribution appear to plan substantial bequests. Mariger devotes the latter part of his book to studying the implications of his estimated consumption model for the effects of government fiscal policies. More specifically, he simulates the model to infer the effects of government tax/debt policy, as well as those of the social security system, on aggregate savings.

Book Description
The main purpose of Lectures on Macroeconomics is to characterize and explain fluctuations in output, unemployment and movement in prices. Lectures on Macroeconomics provides the first comprehensive description and evaluation of macroeconomic theory in many years. While the authors' perspective is broad, they clearly state their assessment of what is important and what is not as they present the essence of macroeconomic theory today.The main purpose of Lectures on Macroeconomics is to characterize and explain fluctuations in output, unemployment and movement in prices. The most important fact of modern economic history is persistent long term growth, but as the book makes clear, this growth is far from steady. The authors analyze and explore these fluctuations. Topics include consumption and investment; the Overlapping Generations Model; money; multiple equilibria, bubbles, and stability; the role of nominal rigidities; competitive equilibrium business cycles, nominal rigidities and economic fluctuations, goods, labor and credit markets; and monetary and fiscal policy issues. Each of chapters 2 through 9 discusses models appropriate to the topic. Chapter 10 then draws on the previous chapters, asks which models are the workhorses of macroeconomics, and sets the models out in convenient form. A concluding chapter analyzes the goals of economic policy, monetary policy, fiscal policy, and dynamic inconsistency. Written as a text for graduate students with some background in macroeconomics, statistics, and econometrics, Lectures on Macroeconomics also presents topics in a self contained way that makes it a suitable reference for professional economists.
