Six new aggregate measures capturing various dimensions of governance provide new evidence of a strong causal relationship from better governance to better development outcomes. In a cross-section of more than 150 countries, Kaufmann, Kraay, and Zoido-Lobaton provide new empirical evidence of a...

This paper reports on the latest update of the Worldwide Governance Indicators (WGI) research project, covering 212 countries and territories and measuring six dimensions of governance between 1996 and 2006: Voice and Accountability, Political Stability and Absence of Violence, Government...

It is well known that there is a strong positive correlation between per capita incomes and the quality of governance across countries. Kaufmann and Kraay propose an empirical strategy that allows separation of this correlation into (1) a strong positive causal effect running from better...

Updated governance indicators report estimates of six dimensions of governance for 175 countries in 2000-01. They can be compared with those constructed for 1997-98. Kaufmann, Kraay, and Zoido-Lobaton construct aggregate governance indicators for six dimensions of governance, covering 175...

Kaufmann, Kraay, and Mastruzzi present estimates of six dimensions of governance covering 199 countries and territories for four time periods: 1996, 1998, 2000, and 2002. These indicators are based on several hundred individual variables measuring perceptions of governance, drawn from 25...

This chapter addresses the history, use and significance of the term transaction costs. Few words in the economic language have been more abused or fought over and this is shown to result from the emergence of two distinct definitions and uses. The ‘Neoclassical’ definition rests on the...

Kaufmann, Kraay and Mastruzzi present the newly updated estimates of six dimensions of governance covering 209 countries and territories for five time periods: 1996, 1998, 2000, 2002 and 2004. These indicators are based on several hundred individual variables measuring perceptions of governance,...

To the uninitiated, transaction costs are often mysterious at best and dubious at worst. Even among economists who use the term often, there are misunderstandings as to what transaction costs actually are. I argue that much of the transaction cost "image" is caused by the lack of a workable...

In standard models of contracts, efficient incentives require the promisor to pay damages for non-performance and the promisee to receive no damages. To give efficient incentives to both parties, we propose a novel contract requiring the promisor to pay damages for nonperformance to a third...

The authors report on the latest version of the worldwide governance indicators, covering 213 countries and territories and measuring six dimensions of governance from 1996 until end-2005: voice and accountability, political stability and absence of violence, government effectiveness, regulatory...
