Book Description
This paper builds a framework for the analysis of macroeconomic fluctuations that incorporates the endogenous determination of the number of producers over the business cycle. Economic expansions induce higher entry rates by prospective entrants subject to irreversible investment costs. The sluggish response of the number of producers (due to the sunk entry costs) generates a new and potentially important endogenous propagation mechanism for real business cycle models. The stock-market price of investment (corresponding to the creation of new productive units) determines household saving decisions, producer entry, and the allocation of labor across sectors. The model performs at least as well as the benchmark real business cycle model with respect to the implied second-moment properties of key macroeconomic aggregates. In addition, our framework jointly predicts a procyclical number of producers and procyclical profits even for preference specifications that imply countercyclical markups. When we include physical capital, the model can reproduce the variance and autocorrelation of GDP found in the data.

Book Description
"This paper studies the role of endogenous producer entry and product creation for monetary policy analysis and business cycle dynamics in a general equilibrium model with imperfect price adjustment. Optimal monetary policy stabilizes product prices, but lets the consumer price index vary to accommodate changes in the number of available products. The free entry condition links the price of equity (the value of products) with marginal cost and markups, and hence with inflation dynamics. No-arbitrage between bonds and equity links the expected return on shares, and thus the financing of product creation, with the return on bonds, affected by monetary policy via interest rate setting. This new channel of monetary policy transmission through asset prices restores the Taylor Principle in the presence of capital accumulation (in the form of new production lines) and forward-looking interest rate setting, unlike in models with traditional physical capital. We also study the implications of endogenous variety for the New Keynesian Phillips curve and business cycle dynamics more generally, and we document the effects of technology, deregulation, and monetary policy shocks, as well as the second moment properties of our model, by means of numerical examples."--abstract.

Book Description
Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.

Book Description
We study the stochastic behavior of a dynamic general equilibrium model with monopolistic competition. Each seller sells his product in the consumption goods as well as the investment goods market and has market power in both. Consumers derive utility from a constant elasticity of substitution (CES) aggregate of all the consumption goods and augment their capital stock by a CES aggregate of all the investment goods. We analyze the equilibrium of this economy allowing for an endogenous determination of the number of firms and therefore of products. The principal effect we wish to highlight is the endogenous propagation and magnification of technology and preference disturbances through product space variations.

Book Description
We combine a structural model with cross-sectional micro data to identify the causes and consequences of rising concentration in the US economy. Using asset prices and industry data, we estimate realized and anticipated shocks that drive entry and concentration. We validate our approach by showing that the model-implied entry shocks correlate with independently constructed measures of entry regulations and M&As. We conclude that entry costs have risen in the U.S. over the past 20 years and have depressed capital and consumption by about seven percent.

Book Description
The NBER Macroeconomics Annual provides a forum for important debates in contemporary macroeconomics and major developments in the theory of macroeconomic analysis and policy that include leading economists from a variety of fields. The papers and accompanying discussions in NBER Macroeconomics Annual 2007 address exchange-rate models; implications of credit market frictions; cyclical budgetary policy and economic growth; the impacts of shocks to government spending on consumption, real wages, and employment; dynamic macroeconomic models; and the role of cyclical entry of new firms and products on the nature of business-cycle fluctuations and on the effects of monetary policy.

Book Description
This is a key year for the evolution of international markets. The global economy is experiencing the most severe downturn since the thirties, it is temporarily leaving a path of sustained growth that characterized the last decades, and is facing an impressive decline of trade between countries. Banks are going bankrupt, the stock market has crashed, rms are going out of bu- ness or drastically reducing their production and exports, workers are being red and investment in new business creation or innovation is shrinking. Meanwhile, consumers con dence has dropped at its minimum, aggregate demand has been declining for months and expansionary policies and int- national coordination have failed to counteract the crisis until now. It is quite likely that all this will change sooner or later, but at the end of this crisis our understanding of the macroeconomy may change as well. In front of these crucial events, this book is not an attempt at proposing a radically new way of interpreting macroeconomic phenomena, and, as a m- ter of fact, it is not even a book on macroeconomic theory. My more modest goal is to collect a number of insights derived from recent research on the role of competition and innovation in the analysis of three topics: business cycles, trade and growth through innovations.

Book Description
This thesis addresses the role of imperfect competition in business cycles driven by expectations and beliefs about the future state of the economy. It consists of three self-contained papers. The first paper examines the roles of composition of aggregate demand and taste for variety in a real business cycle model with endogenous entries and exits of monopolistically competitive firms. It finds that taste for variety can alone make the economy susceptible to endogenous (sunspot driven) business cycles. Importantly, in light of recent research suggesting that aggregate markups in the U.S. are procyclical, sunspot equilibria emerge with procyclical markups that are within empirically plausible ranges. The second paper considers aggregate markup variations in business cycles driven by news about future total factor productivity. It shows that the addition of endogenous countercyclical markups and investment adjustment costs allows the standard one-sector real business cycle model to generate empirically supported expectations driven fluctuations. The simulated model reproduces the regular features of U.S. aggregate fluctuations. The third paper investigates the role of product variety effects and variable markups in expectations-driven business cycles. It demonstrates that taste for variety and investment adjustment costs allow the otherwise canonical real business cycle model to display quantitatively realistic fluctuations in response to news about future total factor productivity. Moreover, the interaction between price-cost decisions and firm entry and exit allows such business cycles to occur for empirically plausible levels of procyclical markups and variety effects.
