Determinants of energy use in the informal food sector

Although enterprises in the informal food sector require energy to transform, cook and process food, energy-use patterns in this sector are not well understood by policymakers and the local-level authorities who regulate their trading activities. This paper reviews relevant literature and presents empirical data collected in Rwanda, Senegal and South Africa on the use of traditional and modern energy sources by informal food sector operators. Our sample includes male- and female-operated enterprises in the urban centres of three African countries where the informal food sector is important, not only for providing the convenience of affordable and readily prepared meals, but also as a source of income for women and men in developing countries. Multiple fuel-use and energy-stacking strategies are common among informal food enterprises and policy needs to acknowledge this if it is to intervene in ways that will benefit both enterprises and regulators.     

Does income inequality increase charitable giving?

Do households react to changes in the distribution of income in their localities by changing their charitable giving? The theoretical prediction of the effects of income inequality on giving is unclear. We study how changes in income inequality measured at the neighbourhood and municipality levels affect charitable giving by households in Canada between 1991 and 2006. We find that increases in inequality increase giving. Results are sensitive to the geographic dispersion of low‐ and high‐income households in neighbourhoods within a municipality. The effect on donations is smaller in areas with high levels of inequality at both neighbourhood and municipality levels.     

The Case Against a U.S.-Arms Monopoly

The U.S. government is the dominant player in the global arms market. Existing literature emphasizes the many benefits of an international U.S. government arms monopoly including: regional and global balance, stability and security, the advancement of U.S. national interests, and domestic economic benefits from international sales. The purpose of this paper is to balance this largely one-sided treatment of the U.S. government’s dominant position in the international arms market. We discuss several negative consequences and costs associated with U.S. arms sales which call into question the net benefit of the U.S. government’s control over global arms.     

The influence of executive cognition on competitive dynamics

Prior competitive dynamics research has drawn on theories of information processing to model the subjective antecedents of executives' retaliation choices. This prior work has made great progress in developing our understanding of the retaliation choices most firms will make to a given type of attack. What the information processing perspective has not been able to do is explain firm‐specific behavior to predict which competitive moves individual firms will challenge, or explain why individual firms differ in the types of actions that they are most likely to challenge. The goal of this paper is to sharpen the theoretical and empirical focus on predicting firm‐level retaliation proclivities. We leverage managerial cognition research to examine the relationship between firm‐level differences in the cognitive frameworks that executives possess, and firm‐level differences in whether and how quickly firms challenge a market move. Results from a longitudinal study of the airline industry suggest that the addition of a cognitive perspective provides important insights into competitive retaliation.

Urban encroachment,forest regrowth and land-use institutions: Does zoning matter?

As concern grows regarding urban sprawl and forest and agricultural land preservation, the effectiveness of land-use policies in shaping land-use change warrants further study. We evaluate the impact of county-level zoning laws, the most predominant land use policy in the USA, and land rents on the relative amounts of forest, agricultural, and developed land, while controlling for demographic information and taxation rates. Over the past decades, southern Indiana has experienced forest regrowth on private lands, but this regrowth has declined in recent years with increased conversion of open space for urban residential development. We develop a model of land-use shares in 40 southern Indiana counties based on the net benefits to agriculture, forestland, and urban uses using a maximum likelihood estimation of a Dirichlet distribution. We find agricultural land rent and indicators of land productivity are the most important predictors of the proportion of agriculture and urban uses. Forest use is better explained by shifting regional economic structure and hilly terrain. Counties with a greater proportion of their work force in the service sectors have a greater proportion of land forested. Finally, to some extent zoning may protect agricultural land in the region, although land rents, land characteristics, and population are strong predictors of the ratio of agriculture to urban use.     

The impact of cost on the choice of university: evidence from Ontario

Abstract. This paper provides the first Canadian study of the link between cost to the student and the choice of university. Over the past two decades, there has been a substantial increase in the differences among Ontario universities in ‘net cost’ defined as tuition and fees minus the expected value to an academically strong student of a guaranteed merit scholarship. Our estimates generally indicate no relationship between net cost and the overall share of strong applicants that a university is able to attract. An increase in net cost is associated with an increase in the ratio of strong students from high‐income neighbourhoods to strong students from middle‐income and low‐income neighbourhoods in Arts and Science programs but not in Commerce and Engineering. Finally, more advantaged students are more likely to attend university, but merit aid is not of disproportionate benefit to those from more economically advantaged backgrounds, given registration.

Where a contract is signed determines its value: Chinese provincial variation in utilized vs. contracted FDI flows

There are major differences between ex ante corporate investment plans and ex post investments. The case of China is useful for understanding this problem because there is substantial time series and cross sectional variation in the ratio of utilized to contracted FDI (UC ratio), which is less than one in most province-year observations. Provinces may believe that they are rewarded for reporting higher levels of contracted FDI, which would lead to lower UC ratios and higher policy incentives in subsequent years. Alternatively, provinces may be rewarded for reporting data more accurately, which would lead to higher UC ratios and policy incentives in subsequent years. Empirical analysis supports the second, institutional theory and suggests that provinces may increase their rate of utilizing pledged FDI by strengthening their legal systems and reducing government bureaucracy.
