In aggregate U.S. data, exogenous shocks to labor productivity induce highly persistent and hump-shaped responses to both the vacancy- unemployment ratio and employment. We show that the standard version of the Mortensen-Pissarides matching model fails to replicate this dynamic pattern due to...

This paper extends the standard Real Business Cycle model to incorporate sectoral shifts in unemployment. Using relative sectoral technology and sectoral tastes shocks, combined with labor adjustment costs across sectors, we assess the possibility of generating persistent aggregate unemployment....

This work is focused on identifying a circular pull production control system (PPCS) and make emphasis on the presence of a stability attribute. It is an introductory paper to an extended study of macroeconomic financial stability in a physically open but systemic closed system. Previous work...

This paper studies the effect of local trade networks on the spatial distribution of employment in a Cooper and John (1988) type model with effective demand externalities. It is shown that, if labor can be hired in continuous quantities, then the long run spatial distribution of employment is...

This paper presents a sequential model suited to analyze transitions between equilibria. Disequilibrium dynamics are obtained from a standard monopolistic competition model, by introducing a sequential structure and reasonable hypotheses about technology, finance constraints, expectation...

This paper studies the effects of local interactions on the distribution of employment in a Keynesian-type model with strategic complementarities. It is shown that rational expectations generate symmetric equilibria for any interaction structure except autarky. Under adaptive expectations, the...

We utilize a large establishment-level panel dataset to explore the links between gross job flows and gross worker flows. Our findings have relevance for models of job creation and job destruction, and labour reallocation. We find churning flows (the difference between worker and job flows at...

Prevailing trade theory is a neglected stepchild of economics. Micro rejects the sole reason for trade’s occurrence. It declares zero profit in equilibrium. Monetary theory and macroeconomics dismiss concerns of trade financing. They assert that money has nothing to do with traded output, but...

We provide a matching model where identical workers are embedded in ex- ante identical social networks. Job arrival rate is endogeneous and wages are bargained. We study the evolution of networks with time and characterize the equilibrium distribution of unemployment rates across networks. We...

This paper provides a simple matching model in which unemployed workers and employers in large firms can be matched together through social networks or through more "formal" methods of search. We show that networks do not necessarily add new externalities and that some results previously...
