Farm households' participation in rural non-farm employment in post-war Rwanda: Drivers and policy implications

Despite the post-war government's unprecedented efforts to stimulate growth of the rural non-farm (RNF) sector in Rwanda, evidence suggests that participation in this sector remains low compared with other developing and transition economies. This study investigates the micro and meso-level factors defining farm household's capacity and incentives to participate in RNF employment in the post-war Rwanda. Based on the household's time allocation theory, this study employs household survey data collected in Gisagara District in a double-hurdle regression. The results reveal that female-headedness, labour availability, education, social networks, access to finance and rural towns increase the probability of participating in RNF activities, whereas for participating households, the time allocated to RNF activities tends to decrease with age, land productivity, distance to market and dispersed settlements. The article concludes with key implications for rural development policies such as basic education and umudugudu settlements.     

Immigration and African American Wages and Employment: Critically Appraising the Empirical Evidence

This paper critically assesses the empirical evidence on the relationship between immigration and African American employment. Studies using various methodologies and data are reviewed: natural experiments, time series, and cross-sectional studies of local labor markets and intertemporal changes in the national labor market. We find that for African Americans as a whole, immigration may have little effect on mean wages and probability of employment. However, there is some evidence that immigration may have had an adverse impact on the labor market outcomes of African Americans belonging to low education-experience groups. However, even this modest conclusion must be qualified: the literature has many unresolved econometric issues that might easily undermine the received wisdom.     

Parasoziale Meinungsführerschaft

In a democratic society, the media operate as a public space in which political and social topics are discussed. As media communicators influence and restrict both the topics of discussion and the amount of information available from in the media, they exert a substantial influence on the recipients’ formation of political opinion. The present study examines this impact by integrating the theoretical concepts of opinion leadership and parasocial relationship, resulting in a phenomenon referred to as parasocial opinion leadership. Based on the results of a qualitative survey of recipients, the concept was then substantiated. Parasocial opinion leadership is based on viewer’s perceptions and comes into existence, if (1) a recipient ascribes certain attributes to a media communicator based on a parasocial relationship; which (2) allows for a gradual influence of the media personality on the recipient’s opinions and attitudes by fulfilling at least one of the three functions information and reduction of complexity, orientation or arousal of interest.     

Transatlantic Differences in Labour Markets: Changes in Wage and Non-Employment Structures in the 1980s and the 1990s

Abstract. Rising wage inequality in the United States and Britain and rising continental European unemployment have led to a popular view in the economics profession that these two phenomena are related to negative relative demand shocks against the unskilled, combined with flexible wages in the Anglo-Saxon countries, but wage rigidities in continental Europe ('Krugman hypothesis'). This paper tests this hypothesis based on seven large person-level data sets for the 1980s and the 1990s. I use a more sophisticated categorization of low-skilled workers than previous studies, which exhibits differences between German workers with and without apprenticeship training, particularly in the 1980s. I find evidence for the Krugman hypothesis when Germany is compared with the United States. However, supply changes differ considerably between countries, with Britain experiencing enormous increases in skill supply explaining the relatively constant British skill premium in the 1990s.

Methods for Generating Longitudinally Correlated Binary Data

The analysis of longitudinally correlated binary data has attracted considerable attention of late. Since the estimation of parameters in models for such data is based on asymptotic theory, it is necessary to investigate the small‐sample properties of estimators by simulation. In this paper, we review the mechanisms that have been proposed for generating longitudinally correlated binary data. We compare and contrast these models with regard to various features, including computational efficiency, flexibility and the range restrictions that they impose on the longitudinal association parameters. Some extensions to the data generation mechanism originally suggested by Kanter (1975) are proposed.     

Effect of different types of feedback on the level of auditors' configural information processing

Previous audit judgement research has emphasized the importance of auditors processing information configurally (i.e. jointly considering the impact of different cues). This paper examines the impact of four different forms of feedback (outcome, task properties, cognitive and combined) on increasing the extent of configural information processing by auditors. We find that task properties, cognitive and combined (task properties plus cognitive) feedback all lead to increased configural information processing. There is no impact of outcome feedback. We also find that the extent of configural processing is positively associated with our measure of judgement performance. We discuss the implications of the results for audit firms.

A brief background on the conference is given, and a summary of the papers offered in this special issue is provided.     

ENDOGENOUS PUNISHMENTS IN AGENCY WITH VERIFIABLE EX POST INFORMATION*

The article studies an adverse selection model in which a contractible, imperfect signal on the agent's type is revealed ex post. The agent is wealth constrained, which implies that the maximum penalty depends on the contracted transaction (e.g., the volume of trade). First, we show that the qualitative effects of the signal can be unambiguously tied to the nature of the problem (e.g., whether the agent is in a “buyer” or a “seller” position). Second, the distortions caused by informational asymmetries may become more severe although more information is now available. Finally, the signal can actually serve to increase the agent's informational rents.     

Bertrand–Edgeworth Duopoly with Buyouts or First Refusal Contracts

In this game the players are firms involved in a Bertrand–Edgeworth duopoly market. Payoffs to the low priced firm depend only on the own price, whereas the payoff to the high priced firm depends on both its own price and the price of the opponent. The price of the opponent enters the payoff function of the high priced firm through buyout or a first refusal contract. Only when the total capacity in the market is less than the output in a monopoly situation, there is an equilibrium in pure strategies.Journal of Economic LiteratureClassification Numbers: C72, D43, L12.
