Policies to stimulate export growth and diversify the composition of exports in South Africa are now high on the government’s agenda. In order to understand exporting and its impact on job creation, one needs to understand how firms function, what determines, or constrains, exporting at the...

We show in the Chinese Annual Survey of Industrial Firms that size distributions of non-exporters and exporters have different shapes, which can only be explained by assuming that their productivity distributions have different shapes. Empirical estimations verify this assumption. This paper...

We construct a simple model to demonstrate how the firm-level degree of scale economies (D-SE) is determined when firms make technology choice. In particular, we illustrate the importance of external factors that affect the efficiency of firms' technology choice, such as public knowledge stock,...

This paper provides the first evidence about pure exporters (i.e., firms exporting all of their output to the foreign market) -- a phenomenon overlooked and cannot be explained in the existing literature. It then offers a generalized model of Melitz (2003) for examining the existence and...

This paper quantifies the separate contribution of idiosyncratic productivity and demand growth on aggregate Chinese exports. We develop firm, product, market and year specific measures of productivity and demand. We use these measures to document a number of novel findings that distinguish the...

This paper presents an analysis of the crucial relationship between innovation, productivity, and export in SMEs. The primary aims of this study are 1) to evaluate the role of innovation in the premium export; and 2) to test the hypothesis of firm conscious self-selection on willing to export....

The Hicks or direct elasticity of substitution is traditionally derived from the production function. This paper exploits duality theory to present a more general derivation from the input distance function, which is exactly dual to the Shadow Elasticity of Substitution. The new elasticity is...

Most traditional explanations for the decreasing aggregate output volatility - so-called "Great Moderation" - fail to accommodate, or even directly contradict, another aspect of empirical data: the average sales volatility for publicly-traded US firms has been increasing during the same period....
