We present a new method for imposing and testing concavity of a cost function using asymptotic least squares, which can easily be implemented even for cost functions which are nonlinear in parameters. We provide an illustration on the basis of a (generalized) Box-Cox cost function with six...

This paper is concerned with measuring and influencing the direction of technological change. First, it provides a comprehensive assessment of the factor bias of technological change using panel data from the World Input-Output Database (WIOD) for 25 EU countries from 1995 to 2009. We measure...

The paper studies the relationship between inequality and economic growth. This is done in a two sector model of endogenous growth with agents characterized by heterogeneity of factor endowments. The private sector consists of a large number of competitive firms who produce the only final good...

We provide a comprehensive survey of the recent literature on the link between productive government expenditure and economic growth. Starting with the seminal paper of Robert Barro (1990) we show that an understanding of the core results of the ensuing contributions can be gained from the study...

Public-private partnerships (PPPs) involve the supply by the private sector of infrastructure and services deriving from infrastructure assets which have traditionally been supplied by the public sector. PPPs are spreading all over the world. It may be quite plausible that such arrangements were...

The quality of goods provided by public utilities depends on infrastructure features and operational inputs. I compare the economic efficiency that results from price ceilings and minimum quality standards (i.e., compliance with environmental, chemical, and performance standards and norms)...

Explication of reality may draw tools outside the phenomenon. That is the essence of case study, and the epistemological motivation of this paper. The paper illuminates the space of PPP policy in the UK. Yet, that illumination raises questions that stand to guide other countries, and the paper...

The paper examines the politics of infrastructure in the post-privatisation era. It shows the tensions between the interests of private investors and the expectations of the citizenry for the assembly of a raft of capital assets that collectively underpin the operation of liveable sustainable...

Using a two-country two-good model, we examine the welfare effects of foreign aid that facilitates factor movement between industries in the recipient country. The government of the donor country produces a public input, which the recipient's government is forced to purchase by spending aid as...

The role of fiscal policy is examined when public goods provide both productive and utility services. In the presence of congestion, the consumption tax is shown to be distortionary. Optimal fiscal policy involves using consumption-based instruments in conjunction with the income tax. An income...
