Microeconomic lumpiness matters for macroeconomics. According to our DSGE model, it is responsible for 92 percent of the smoothing in the investment response to aggregate shocks, and it introduces important nonlinearities and history dependance in business cycles and policy sensitivity. General...

We develop a model of state-dependent pricing that we can log-linearize and compare to the standard Calvo model. In one extreme case, money is neutral with state-dependent pricing even though the probability of price adjustment is constant as in the Calvo model. We use this example to illustrate...

The main contribution of this work is to provide a dynamic general equilibrium model of asset allocation, allowing to reconcile economic theory with several puzzling contradictions recently pointed out in the literature: (i) the asset allocation puzzle, (ii) the observed time-variation in...

The main goal of this paper is to measure the welfare costs of business cycles in a production economy in which the representative agent has low risk aversion and - at the same time - the equity premium and the co-movements of aggregate quantities and market returns are comparable to what...

The path of economic development for rich industrialized countries is typically to transit from farming to manufacturing to services. To do so requires corresponding productivity gains to pull the economy from one sector to the next one. For example, the US and Japan developed their...

Although it is well known that aggregate variables have slow-moving stochastic components, research on macroeconomic fluctuations has focused primarily on high-frequency movements of the data. I document some interesting lower-frequency facts in U.S. postwar data and investigate whether dynamic...

In 1910 the average American city was a small and densely populated place where the dominant form of intracity transportation was the electric streetcar. Despite the release of the Model T in 1908, less than one percent of Americans owned a car. In contrast, by 1970, almost every family in the...
