Mobile Phones and Radios: Effects on Transactions Costs and Market Participation for Households in Northern Ghana

The literature on agricultural markets suggests that transactions costs are the main obstacles preventing households from participating in agricultural markets. We examine the impact of the recent massive penetration of information communication technologies (ICTs), particularly mobile phones and radios, in developing countries to investigate the role of information in economic transactions and participation in food crop markets. To fully capture market participation behaviours, the current theoretical framework on market participation and transactions costs is extended to include those households that sell and buy in the same time period. We correct for endogeneity and selectivity throughout our models. We used a novel dataset of 393 households in northern Ghana with detailed information on market transactions and ICTs usage. Results show that receiving market information via mobile phones has a positive and significant impact on market participation, with a greater impact for households with a surplus of food crops. We find that radios have a larger impact on the quantity traded. This may reflect the nature of mobile phones in reducing searching costs, whereas radios provide an updated and regular flow of information which affects the pattern of crops consumed and sold. We also emphasise that the most significant factor is how ICTs are used, rather than their ownership.     

A metacultural approach to predicting self-employment across the globe

Drawing from neo-institutional theory, we examine the relationship between preference for entrepreneurship and actual entrepreneurship behavior across multiple countries and cultures. We elucidate how multiple societal-level cultural models, namely Hofstede, Global Leadership and Organizational Behavior Effectiveness (GLOBE), and Schwartz affect the individual-level process connecting expressed preference for self-employment and actual behavior. Our hypotheses were tested using a multilevel technique on a sample of 20,755 individuals across 24 countries. The findings indicate that the moderating effect of predominant cultural cognition is partially supported. Contributions and implications for theory and practice are also discussed.     

The Great Inflation and the Greenbook

Can the story of evolving Federal Reserve beliefs in The Conquest of American Inflation simultaneously explain the Great Inflation and the forecasts published in the Greenbook during that time? If Sargent is correct then evolving beliefs should be reflected not only in policy outcomes but also in Greenbook forecasts. In this paper they are. By conditioning on the Greenbook, it is show that both inflation outcomes and Greenbook forecasts can be rationalised by evolving beliefs. The results improve on recent empirical evidence that has been criticised for relying on unrealistic beliefs that produce forecasts inconsistent with the Greenbook.

Semi-unionized bargaining with endogenous membership and management opposition

This paper develops a model of open shop unions and efficient bargain, in which there is a social custom to unionize and the firms can pay wage premiums to dissuade union membership. If firms actively oppose unions, the union density turns out to be affected by changes of the product price and the reservation wage, and it is not always positively correlated with the workers' income share. Moreover, the model provides a rationale for higher union density in centralized as opposed to decentralized bargaining systems.I would like to thank Robert Boyer, Hans Peter Grüner, Roger Guesnerie, and two referees for helpful comments and suggestions. All remaining errors are mine. Financial support from the Commission of the European Communities (SPES-915028) is gratefully acknowledged.     

The Rise and Likely Fall of the German Income Tax, 1958-2005

Data from official statistics and tax laws are exploited todescribe fifty years of income taxation in Germany, with a focuson its role as a fiscal and distributive tool. The temporalpattern that emerges from the data is one of a golden age ofthe German income tax, followed by a slow shift towards a majorcrisis. The turning point on the income-tax path seems to haveoccurred in 1986. I put forward the thesis that this downturnwas the outcome of a long-term change in the balance of politicalpower. That change is probably rooted in structural breaks thatoccurred in the German economy during the 1970s and early 1980s.(JEL D31, D72, H23}.     

Hormone beef, chlorinated chicken and international trade

We study international trade in innovative goods subject to uncertain consumer health effects. Such goods are often at the center of international trade disputes. We show that an interesting form of protectionism may arise because of scientific uncertainty. A free-riding effect is identified, implying more conservative behavior by countries. We also study the role of producers (lobbies) in providing valuable information, finding that the innovative lobby has an advantage in providing information as compared with the lobby producing the ‘traditional’ good. Moreover, lobbies disclose more information when the health effects are long lasting.     

Voluntary Provision of Public Goods and Technology

This paper highlights issues in the theory of voluntary provision of public goods, building on the investigation by Peacock in connection with the contributions by Coase and Buchanan. Our goal is twofold. We first draw attention to the early literature investigating the provision of public goods and to the successive theoretical analysis. We then focus on the impact of technology on supply and demand. Examples of different types of public goods are provided, with special attention to the cultural sector, to investigate whether and how technology affects the efficiency and the effectiveness of the related public goods provision. The implementation and exploitation of technological advancements are investigated in view of the role of different actors (public, private) at different levels of government.     

Island cruise tourism development: a resident's perspective in the context of Italy

Most studies that examine tourism impacts and community attitudes have been carried out from the perspective of the tourism sector as a whole, with very few papers focusing on specific types of tourism and/or analysing tourists' preferences for specific types of tourism segment. This paper discusses some pertinent issues in relation to cruise tourism development and community attitudes in a port of call cruise destination located in the island of Sicily (Southern Italy). Specifically, this study was carried out using a quota random sample of 1500 responses, which is representative of the population of Messina at 1% level. Findings show that residents express an overall positive attitude towards cruise tourism development even if it is not the most preferred when compared to other types of tourism (cultural tourism, sport tourism, and sun and sea tourism). Further, they highlight that significant differences based on socio-economic and demographic characteristics (age, gender, reliance on cruise-related employment, level of education, geographical proximity to tourist areas and port, length of residency and frequency of interaction with tourists) exist in residents' perceptions and attitudes towards cruise tourism development. Implications for policy-makers are discussed and suggestions for further research are given.
