This paper proposes a new unit root test in the context of a random autoregressive coefficient panel data model, in which the null of a unit root corresponds to the joint restriction that the autoregressive coefficient has unit mean and zero variance. The asymptotic distribution of the test...

This paper proposes two new unit root tests that are appropriate in the presence of an unknown number of structural breaks. One is based on a single time series and the other is based on a panel of multiple series. For the estimation of the number of breaks and their locations, a simple...

In practice, targeted monitoring seems to be a strategy frequently used by regulators. In this paper, we study the effects of targeted monitoring strategies on the adoption of a new abatement technology and, consequently, on the aggregate emissions level when firms are regulated with uniform...

In a natural field experiment, we tested whether being alone or in a group had an effect on prosocial behavior as expressed in donations to a recreational park. We also explored whether the presence of people exogenous to the group at the time of the donation had any behavioral effect. Our first...

Social preferences have been shown to be an important determinant of economic decision making for many adults. We present a large-scale experiment with 883 children and adolescents, aged eight to seventeen years. Participants make decisions in eight simple, one-shot allocation tasks, allowing us...

The question of whether laws affect attitudes has inspired scholars across many disciplines, but empirical knowledge is sparse. Using longitudinal survey data from Norway and Sweden, collected before and after the implementation of a Norwegian law criminalizing the purchase of sexual services,...

International trafficking in humans for sexual exploitation is an economic activity driven by profit motives, and up to four million people are estimated to be exploited by human traffickers each year. Laws regarding commercial sex influence the profitability of trafficking and may thus affect...

The aim of the present paper is to investigate whether households relocated to governmentbuilt village settlements, as part of Rwanda’s Villagisation programme (‘Imidugudu’), diversify into non-farm income-generating activities to a greater extent than other rural households in Rwanda, and...

In the Contingent Valuation Method (CVM), both the goods being valued and the payment vehicles used to value them are mostly hypothetical. However, although numerous studies have examined the impact of experience with the good on the willingness to pay, less attention has been given to...

The new fertilizer subsidies in Sub-Saharan Africa are intended to increase agricultural production and ensure fertilizer market development. Fertilizer adoption requires complementary inputs such as investment in soil and water conservation for efficient and optimal nutrient uptake, and many...
