It is shown how one can effectively use cross-section data in modelling the change over time in aggregate consumption expenditure of a heterogeneous population. The starting point of our aggregation analysis is a dynamic behavioral relation on the household level. Based on certain hypotheses on...

This paper reviews household property risk management and estimates normatively optimal choice under theoretical assumptions. Although risk retention limits are common in the financial planning industry, estimates of optimal risk retention that include both financial and human wealth far exceed...

We examine a dynamic disclosure model in which the value of a firm follows a random walk. Every period, with some probability, the manager learns the value and decides whether to disclose it. The manager maximizes the market perception of the firm's value, which is based on disclosed...

It is well known from time series analysis that shocks to aggregate output have very persistent effects. This paper argues that the relation between the expected growth rate of a firm and its size provides a microfoundation for such aggregate persistence. The empirical evidence indicates that...

A well-known fact in the time series of aggregate output is the persistence of shocks. This paper argues that the empirical relation between the expected growth rate of a firm and its size provides a microfoundation of aggregate persistence. In fact, the empirical evidence claims that small...
