Norwegian business spending on R&D is low by OECD standards. To stimulate business R&D, in 2002 the Norwegian government introduced a tax-based incentive, SkatteFUNN. We analyze the effects of SkatteFUNN on the likelihood of innovating and patenting. Using a rich database for Norwegian firms, we...

This paper asks whether income mobility in South Africa over the last decade has indeed been as impressive as currently thought. Using new national panel data (NIDS), substantial measurement error in reported income data is found, which is further corroborated by a provincial income data panel...

While the majority of micro studies finds that rural education increases agricultural productivity, various recent cross-country regressions analysing the determinants of agricultural productivity were only able to detect insignificant or even surprising negative effects of schooling. In this...

This article describes the consumption model and inequality study of Chapter 2 in the author's unpublished Ph.D. dissertation submitted at the Dept. of Economics, University of California, Berkeley. The Norwegian Research Council and Statistics Norway financed the project; project no....

There is considerable interest in identifying the magnitude of the difference between increases in CPI and costs-of-living, and this article uses the technique proposed by Hamilton (2001) to measure this discrepancy for Norway for the 90s. The method is extended along several dimensions by...

Most micro-level studies on the impact of agricultural technologies build on cross-section data, which can lead to unreliable impact estimates. Here, we use panel data covering two time periods to estimate the impact of tissue culture (TC) banana technology in the Kenyan small farm sector. TC...

In this paper we discuss two types of selection problems. The first problem is motivated by labor market analyses such as the estimation of sector-specific wage equations where the sector for which the wages are observed are chosen by the agents. In contrast to previous formulations which...

Many empirical studies specify outcomes as a linear function of endogenous regressors when conducting instrumental variable (IV) estimation. We show that commonly used tests for treatment effects, selection bias, and treatment effect heterogeneity are biased if the true relationship is...

Offering electricity consumers time-differentiated tariffs may increase demand responsiveness, thereby reducing peak consumption. However, one concern is that time-differentiated tariffs may also attract consumers who benefit because of their consumption pattern, even without a corresponding...
