To date, empirical investigations of trade liberalization under the conditions of increasing returns to scale (IRS) and imperfect competition (IC) have either assumed or imposed the market and productive structures necessary for such a model. However, of the recent IRS/IC models used to simulate...

Using the 1997-1998 New South Wales public-hospitals comparison data, we investigate the hospital-level inefficiency by applying a stochastic-frontier multiproduct cost function. We use a flexible translog cost function to reduce the measurement errors of the outputs of the hospital. The main...

This note provides a useful property of the Allen-Uzawa partials for the translog cost function. It also suggests how the main results extend to any functional form with certain properties. The curvature of the Allen-Uzawa matrix is the same as the curvature of the Hessian matrix. Intuitively...

We use UK micro data to explore whether planning regulation reduced UK retailing productivity growth between 1997 and 2003. We document a shift to smaller shops, particularly within supermarket chains, following a regulatory change in 1996 which increased the costs of opening large stores. This...

This paper presents a tractable formalization and an empirical investigation of the quality-complementarity hypothesis, the hypothesis that input quality and plant productivity are complementary in generating output quality. We embed this complementarity in a general-equilibrium trade model with...

We examine the dramatic expansion in the Turkish higher education system during 2006-2008, which resulted in the establishment of 41 new public universities and a 60% increase in the number of available slots. Using the variation in the exposure intensity of expansion across cohorts and regions,...

This paper evaluates the effectiveness of a widely used sanitation intervention, Community-Led Total Sanitation (CLTS), using a randomized controlled trial. The intervention was implemented at scale across rural East Java in Indonesia. CLTS increases toilet construction, reduces roundworm...

The theory of endogenous technical change has deeply contributed to our understanding of the fundamental sources of economic growth and development. In this chapter we survey important contributions in the field by focussing on the basic structure of endogenous growth models with horizontal as...

We analyse the decision to become an entrepreneur by either taking over an established business or starting a new venture from scratch. A model is developed which predicts how several individual- and firm-specific characteristics influence entrepreneurs' entry mode. The new venture creation mode...

We propose a novel structural method to empirically identify economies of scale in household consumption. We assume collective households with consumption technologies that define the public and private nature of expenditures through Barten scales. Our method recovers the technology by solely...
