We characterize the relationship between the distributions of two variables linked by a
structural model. We then show that, in models of heterogeneous firms in monopolistic …

The Pareto distribution is widely used to model industrial, biological, engineering, and other
various types of data. A new generalized model, namely the neutrosophic Pareto distribution …

The elasticity of exports to exchange rate fluctuations has been the subject of a large body of
literature without a clear consensus emerging. Using a novel sector-level dataset based on …

In this paper, we propose a statistical model to characterize the null hypothesis of the
random product size distribution for multi-product exporters. It serves as a benchmark to test …

Statistical offices frequently use cutoff sampling to determine which businesses in a
population should be surveyed. Examples include business surveys about international …

We provide an overview and synthesis of recent work on models of monopolistic competition
with heterogeneous firms in international trade, paying particular attention to competition …

We explore welfare properties in a firm heterogeneity model with multinational production
and export. The presence of multinational production plays a crucial role in delivering a …

In this paper, we propose a statistical model of multi-product exporters to characterize the
null hypothesis of random product size distribution. It serves as a benchmark to test the …

This paper contributes to the literature on the relationship between innovation and exports
by developing a model that emphasizes the role of product innovation in explaining …

Finding a good parametric approximation to the productivity distribution is a problem of
general interest. This paper argues that heterogeneity in productivity is best captured by …
