This paper shows that goods-market frictions drastically change the dynamics of the labor market, bridging the gap with the data both in terms of persistence and volatility. In a DSGE model with three imperfect markets - goods, labor and credit - we find that credit- and goods-market imperfections are substitutable in raising volatility. Goods-market frictions are however unique in generating persistence. The two key mechanisms generating autocorrelation in growth rates and the hump-shaped pattern in the response to productivity shocks are related to the goods market: i) countercyclical dynamics of goods market tightness and prices, which alter future profit flows and raise persistence and ii) procyclical search effort in the goods market, by either consumers, firms or both, raises both amplification and persistence. Expanding our knowledge of goods market frictions is thus needed for a full account of labor market dynamics.

Building a model with three imperfect markets -- goods, labor and credit -- representing a product's life-cycle, we find that goods market frictions drastically change the qualitative and quantitative dynamics of labor market variables. The calibrated model leads to a significant reduction in the gap with the data, both in terms of persistence and volatility while search models of the labor market fail in one of the two dimensions. Two factors related to goods market frictions generate these results: i) the expected dynamics of consumers' search for goods, itself depending on the income redistributed by firms and the entry of new products; and ii) the expected dynamics of prices, which alter future profit flows.

An integrated framework to study the theoretical and quantitative properties of economies with frictions in labor, financial, and goods markets. This book offers an integrated framework to study the theoretical and quantitative properties of economies with frictions in multiple markets. Building on analyses of markets with frictions by 2010 Nobel laureates Peter A. Diamond, Dale T. Mortensen, and Christopher A. Pissarides, which provided a new theoretical approach to search markets, the book applies this new paradigm to labor, finance, and goods markets. It shows, in particular, how frictions in different markets interact with each other. The book first covers the main developments in the analysis of the labor market in the presence of frictions, offering a systematic analysis of the dynamics of this environment and explaining the notion of macroeconomic volatility. Then, building on the generality and simplicity of the search analysis, the book adapts it to other markets, developing the tools and concepts to analyze friction in these markets. The book goes beyond the traditional general equilibrium analysis of markets, which is often frictionless. It begins with the standard analysis of a single market, and then sequentially integrates more markets into the analysis, progressing from labor to financial to goods markets. Along the way, the book provides a number of useful results and insights, including the existence of a direct link between search frictions and the degree of volatility in the economy.

Emerging economies have high shares of self-employed individuals running owner-only firms who, in contrast to many salaried firms, have little access to formal financing and therefore rely on informal financing (input credit) from other firms. We build a small open economy real business cycle model with labor and financial market frictions where formal credit markets, informal credit, and the structure of the labor market interact. The model successfully replicates the cyclical behavior of sectoral employment, formal credit, and the main macroeconomic aggregates in emerging economies. We show that a countercyclical macroprudential policy that reduces formal credit fluctuations has positive though quantitatively limited effects on consumption and output volatility, but generates larger unemployment fluctuations in response to productivity shocks; the same policy increases labor market and aggregate volatility in response to net worth shocks. The link between input credit and the labor market structure---key for capturing the cyclical dynamics of labor and credit markets in the data---plays a crucial role for these results.

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.

The Oxford Handbook of Computational Economics and Finance provides a survey of both the foundations of and recent advances in the frontiers of analysis and action. It is both historically and interdisciplinarily rich and also tightly connected to the rise of digital society. It begins with the conventional view of computational economics, including recent algorithmic development in computing rational expectations, volatility, and general equilibrium. It then moves from traditional computing in economics and finance to recent developments in natural computing, including applications of nature-inspired intelligence, genetic programming, swarm intelligence, and fuzzy logic. Also examined are recent developments of network and agent-based computing in economics. How these approaches are applied is examined in chapters on such subjects as trading robots and automated markets. The last part deals with the epistemology of simulation in its trinity form with the integration of simulation, computation, and dynamics. Distinctive is the focus on natural computationalism and the examination of the implications of intelligent machines for the future of computational economics and finance. Not merely individual robots, but whole integrated systems are extending their "immigration" to the world of Homo sapiens, or symbiogenesis.

Contemporary general equilibrium theory is characteristically short-run, separated from monetary aspects of the economy, and as such does not deal with long-run problems such as capital accumulation, innovation, and the historical movement of the economy. These phenomena are discussed by growth theory, which assumes a given or shifting production function, and in turn cannot therefore deal with the fundamental problem of growth, namely how the production function is derived. Thus traditional theories have a common weakness in that they divorce real economic growth from the activities of the financial sector. This book provides a much-needed synthesis of growth theory and monetary theory. Professor Morishima draws on the work of Schumpeter, Keynes and the pre-war neoclassical economists to formulate a capital-theoretic general equilibrium theory.

We explore the impact of major labor and product market reforms on current account dynamics using a new “narrative” database of major changes in employment protection for regular workers and product market regulation for non-manufacturing industries covering 26 advanced economies over the past four decades. Our main finding is that product market deregulation is associated with a weakening of the current account, while labor market deregulation is associated with an improvement. These effects are transitory and driven by both saving and investment responses. Labor and product market reforms both have a more positive impact on the current account balance when implemented under weak macroeconomic conditions. Our results are broadly consistent with predictions from recent DSGE models with endogenous producer entry and labor market frictions.
