The most striking difference in corporate-governance arrangements between rich and poor countries is that the latter rely much more heavily on the dynastic family firm, where ownership and control are passed on from one generation to the other. We argue that if the heir to the family firm has no...

A vast empirical literature has documented delayed and persistent effects of monetary policy shocks on output. We show that this finding results from the aggregation of output impulse responses that differ sharply depending on the timing of the shock: when the monetary policy shock takes place...

Systematic differences in the timing of wage setting decisions among industrialized countries provide an ideal framework to study the importance of wage rigidity in the transmission of monetary policy. The Japanese Shunto presents the most well-known case of bunching in wage setting decisions:...

A large literature has documented statistically significant effects of monetary policy on economic activity. The central explanation for how monetary policy transmits to the real economy relies critically on nominal rigidities, which form the basis of the New Keynesian (NK) framework. This paper...

Systematic differences in the timing of wage setting decisions among industrialized countries provide an ideal framework to study the importance of wage rigidity in the transmission of monetary policy. The Japanese Shunto, for example, presents a clear case of bunching in wage setting decisions:...

In the analysis of microarray data, and in some other contemporary statistical problems, it is not uncommon to apply hypothesis tests in a highly simultaneous way. The number, N say, of tests used can be much larger than the sample sizes, n, to which the tests are applied, yet we wish to...

We consider a locally stationary model for financial log-returns whereby the returns are independent and the volatility is a piecewise-constant function with jumps of an unknown number and locations, defined on a compact interval to enable a meaningful estimation theory. We demonstrate that the...

In this paper, we study the excursion time of a Brownian motion with drift outside a corridor by using a four states semi-Markov model. In mathematical finance, these results have an important application in the valuation of double barrier Parisian options. In this paper, we obtain an explicit...
