This paper analyzes the impact of technological diversity on innovation inputs and success using Swiss firm-level panel data. While we do not find any impact of diversity on R&D intensity, we confirm a positive impact of diversity on patent applications as suggested by the literature. However, since patent applications reflect an intermediate innovation input rather than output, we extend the a...

An extensive literature shows that agency issues and transactions costs influence vertical integration. Another mature literature indicates that market structure influences competitive behavior. However, less consideration has been given to how vertical integration and market structure may interact. I address this gap by focusing on the potential for moral hazard caused by intra-firm competitio...

This paper investigates whether the efficiency effect of product market dispersion is a function of the infrastructural and policy environment. We hypothesize that more developed transportation and communication infrastructure and lower government regulation may reduce transaction costs, intensifying the competition associated with a given market structure, and we use data from the recently lib...

Facing a stochastic market wage, which is independent of their own hiring policy, employers offer contracts specifying fixed wage, revenue share and employment duration. In ongoing employment relations it depends on the treatment whether fixed wages can be only increased or also decreased. Will the uncertainty of the future market wage and less wage flexibility lead to temporary employment? And...

This paper compares the out-of-sample forecasting accuracy of five classes of time series models for market shares of the six most important Portuguese car market competitors over different horizons. As representative time series models I employ a random walk with drift (Naive), a univariate ARIMA, a near-VAR and a general BVAR. The out-of-sample forecasts are also compared against forecasts ge...

The paper examines a dynamic model of a financial market with endogenous asset prices determined by short run equilibrium of supply and demand. Assets pay dividends, that are partially consumed and partially reinvested. The traders use fixed-mix investment strategies (portfolio rules), distributing their wealth between assets in fixed proportions. Our main goal is to identify globally evolution...

Prior studies have documented that stock returns are abnormally high during the years following share repurchases and abnormally low following seasoned equity offerings, relative to various benchmarks of expected returns. While we confirm this evidence in the event data as of 2002, we do not find robust long-run abnormal returns following either stock repurchases or issuances after 2002. Instit...

Does Culture Matter? This paper reviews the literature on culture and economics, focusing primarily on the epidemiological approach. The epidemiological approach studies the variation in outcomes across different immigrant groups residing in the same country. Immigrants presumably differ in their cultures but share a common institutional and economic environment. This allows one to separate the...
