We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A key feature is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using detailed US...

We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A new and central economic force is the selection between highand low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using...

Located within a broader project on barriers to entry undertaken for National Treasury, this case study explores the typical challenges faced by new entrants in the supermarket industry in South Africa. It draws insights from the experiences of Fruit and Veg City Ltd. and Choppies Enterprises...

This study is part of the broader barriers to entry project undertaken for the National Treasury and it assesses barriers to entry and expansion into the agro processing sector. It focuses on three agro-processing subsectors; poultry, milling and dairy. The paper draws on interviews conducted...

Employment growth is strongly predicted by smaller average establishment size, both across cities and across industries within cities, but there is little consensus on why this relationship exists. Traditional economic explanations emphasize factors that reduce entry costs or raise...

This paper develops a fully-endogenous, variety-expansion growth model with firm-specific quality heterogeneity, limit pricing, and an endogenous distribution of markups. Trade induces only firms with high-quality products to export, whereas firms with low-quality products serve only the...
