Evidence of the statistical significance of profits in Q regressions remains one of the principal findings in the empirical investment literature. This result is taken to support the view that capital market imperfections are an important element for understanding investment. This paper...

In this paper, we propose to use the Monte-Carlo (MC) test technique to obtain valid p-values when testing for the presence of discontinuities in jump-diffusion models. Indeed, the LR statistic used to test for discontinuities has typically a complex non-standard distribution, for at least two...

We present algorithms for computing the weights implicitly assigned to observations when estimating unobserved components using a model in state space form. The algorithms are for both filtering and signal extraction. In linear time-invariant models such weights can sometimes be obtained...

Consumption is partly a social activity, yet most studies of consumer behavior treat households in isolation. We investigate familial relationships in consumption patterns using a sample of parents and their children from the Panel Study of Income Dynamics. We find a positive and statistically...

This paper deals with the long lasting debate on the exchange rate shocks and price adjustments in a dynamic programming framework. We present a framework where firms face menu costs when they decide change their prices in a competitive environment. The main result of the paper is that band of...

In the course of the analysis of time series of counts the need to test for the presence of a dependence structure arises regularly. Suitable tests for this purpose are analysed in this paper. Their size and power properties are evaluated under various alternatives among which the...

This paper calculates the quantitative significance of the welfare effects of wage compression in Sweden. This is done in a dynamic general equilibrium model with overlapping generations where agents choose both schooling (human capital) and assets (physical capital). This paper shows that when...
