Many countries simultaneously suffer from high rates of inflation, low growth rates of per capita income and poorly developed financial sectors. In this paper, we integrate a microfounded model of money and finance into a model of endogenous growth to examine the effects of inflation and...

In this paper, we develop a general stochastic model of directed search on the job. Like in the analogous models of random search on the job, the state of the economy in our model includes the infinite-dimensional distribution of workers across different employment states (unemployment, and...

In this paper, we construct a tractable search model of money with a non-degenerate distribution of money holdings. We model search as a directed process in the sense that buyers know the terms of trade before visiting particular sellers, as opposed to undirected search that has dominated the...

We compare the welfare effects of different emission-reduction policies in a general equilibrium model with heterogeneous plants. We found that an emission standard could outperform an emission tax or a tradable permit. We characterize the equilibrium conditions for this result to hold. We...

We develop a general equilibrium framework to analyze the relationship between the operation of the financial system, inflation and economic growth. We first investigate the dynamic interactions between financial development and growth by analyzing how financial innovations affect real growth,...

In this paper, we develop a tractable model of the labor market where workers search for jobs both while unemployed and while on the job. Search is directed in the sense that each worker chooses to search for the offer that provides the optimal tradeoff between the probability of obtaining the...

In the last few decades there is a clear shift of employment shares from the manufacturing sector to the service sector in the US and in many industrialized countries. At the same time, the structure of residual wages changes considerably, within and across sectors. To understand the sources of...

I analyze a search equilibrium of a large market where customer relationship arises endogenously together with service priority and sales. A buyer is related to a seller if he just purchased from the seller, and the relationship is broken if the buyer fails to buy from the seller. I prove that...

In the last few decades there is a clear shift of the U.S. economy from the non-service sector to the service sector. We document the patterns of changes in the employment share in services, the transition rates of workers between the two sectors and between different employment status, the...
