This paper examines the effect on productivity of having more near advertising agency neighbors and hence better opportunities for meetings and exchange within Manhattan. We will show that there is extremely rapid spatial decay in the benefits of having more near neighbors even in the close...

This paper provides a model of knowledge sharing and networking among single unit advertising agencies and investigates the implications of this model in the presence of heterogeneity in agencies’ quality. In a stylized screening model, we show that, under a modest set of assumptions, the...

I develop and estimate a model of export dynamics featuring self-discovery that accounts well for new exporter dynamics: (a) continuation rates that are increasing with tenure, and (b) growth rates of export sales that are decreasing with tenure. The option value generated by the acquisition of...

This paper incorporates learning and reputation building into a simple dynamic stochastic model with asymmetric information. We use the model to study a bilateral trade flow influenced significantly by learning and reputation, namely U.S. imports of Japanese cars over the period 1961–2004....

We demonstrate that common modeling assumptions underlying micro-unit productivity indices induce biases in the evolution and decomposition of standard aggregate productivity measures. After controlling for such biases, we decompose aggregate productivity based on groups of economically...

In this paper, we examine an innovative postal export regime that involves both a streamlining of export procedures and provision of intermediation services to investigate how firms' react to changing trade costs and whether and how these firms learn. In so doing, we use a unique dataset that...

In this study, we investigate the relationship between exporting and firm performance using a longer panel dataset of Ethiopian manufacturing firms for the period 1996 - 2009. We test two hypotheses regarding exporting: selection into exporting versus learning by exporting. According to the...

This paper provides evidence that learning about demand is an important driver of firms' dynamics. We present a simple model with Bayesian learning in which firms are uncertain about their idiosyncratic demand parameter in each of the markets they serve, and update their beliefs as noisy...
