We consider a difference-in-differences setting with a continuous outcome, such as wages or expenditure. The standard practice is to take the logarithm of the outcome and then interpret the results as an approximation of the multiplicative treatment effect on the original outcome. We argue that...

A Simulated Maximum Likelihood (SML) estimator for the random coefficient logit model using aggregate data is found to be more efficient than the widely used Generalized Method of Moments estimator (GMM) of Berry-Levinsohn-Pakes (1995). In particular, the SML estimator is better than the GMM...

Development assistance has been criticized for a lack of coordination between aid donors. This paper argues that competition for export markets and political support prevents donor countries from closer coordination of aid activities. To test these hypotheses, we perform logit and fractional...

The paper aims to identify the role of different sources of innovation for the Estonian wood sector. Comparing data from survey of Innovation in Estonian Enterprises 1998 2000 with similar Finnish data reveals that linkages in Estonian forest and wood cluster are relatively weaker regarding...

Within the recent literature studying participation in international markets using micro data, a small number have suggested that firms benefit from their exposure to international markets. One channel considered for this role has been investments in Ramp;D. A common finding in this literature...

Persons with disabilities have relevant working capacity. Employers who recruit those persons assume that their disabilities do not decrease organization's productivity. Persons with disabilities can normally fit into working environment. The studies of employers' attitude towards persons with...

We consider the issue of choosing a subset of locations to construct new housing developments maximizing the satisfaction of potential buyers. The allocation of demands to the selected locations is modeled by a choice model, based on the distance to the location, real-estate prices and incomes....
