Cultural Baggage: Do Immigrants Import Corruption?

Do immigrants undermine culture in a way that destroys productivity in destination countries? Some scholars have argued that because immigrants come from countries with dysfunctional social capital—norms and institutions—they will import it and pollute the social capital in destination countries. One potential channel through which this could occur is corruption. We examine stocks and flows of immigrants over a 20‐year time period to see if corruption increased in destination countries. We generally find that immigration is not associated with increases in corruption. Additionally, we find that immigration tends to decrease corruption in destination countries with low levels of corruption or high levels of economic freedom.     

Endogenous communication among lenders and entrepreneurial incentives

If banks have an informational monopoly about their clients,borrowers may curtail their effort level for fear of being exploitedvia high interest rates in the future. Banks can correct thisincentive problem by committing to share private informationwith other lenders. The fiercer competition triggered by informationsharing lowers future interest rates and future profits of banks.But, provided banks retain an initial informational advantage,their current profits are raised by the borrowers' higher effort.This trade-off determines the banks' willingness to share information.Their decision affects credit market competition, interest rates,volume of lending, and social welfare.     

Cross-Country Polarisation in CO2 Emissions Per Capita in the European Union: Changes and Explanatory Factors

We analyse the degree of polarisation in the international distribution of CO₂ emissions per capita in the European Union. It is analytically relevant to examine the degree of instability inherent to a distribution and, in the analysed case, the likelihood that the distribution and its evolution will increase or decrease the chances of reaching an agreement on climate policy. Two approaches were used to measure polarisation: the endogenous approach, in which countries are grouped according to their similarity in terms of emissions, and the exogenous approach, in which countries are grouped geographically. Our findings indicate a clear decrease in polarisation since the mid-1990s, which can essentially be explained by the fact that the different groups have converged (i.e. antagonism among the CO₂ emitters has decreased) as the contribution of energy intensity to between-group differences has decreased. This lower degree of polarisation in CO₂ distribution suggests a situation more conducive to the possibility of reaching EU-wide agreements on the mitigation of CO₂ emissions.     

Promotion and Fast Food Demand

Many believe that fast food promotion is a significant cause of the obesity epidemic in North America. Industry members argue that promotion only reallocates brand shares and does not increase overall demand. We study the effect of fast food promotion on market share and total demand by estimating a discrete / continuous model of fast food restaurant choice and food expenditure that explicitly accounts for both spatial and temporal determinants of demand. Estimates are obtained using a unique panel of Canadian fast food consumers. The results show that promotion primarily increases demand and has a smaller effect on restaurant market shares.     

The Tourism Penetration Index in Large Islands: The Case of the Dominican Republic

The Tourism Penetration Index (TPI) (McElroy & de Albuquerque, 1998) provides an overall measure of economic, social and environmental impact in small islands. Thus far it has not been used to gauge tourism’s spatial concentration in different regions within a given destination. This study develops a TPI for four regions in the Dominican Republic (DR), and these regional scores are compared with a sample of 42 small islands. Results place Punta Cana in the east among the most penetrated islands/ regions, Puerto Plata/Samana in the north among the intermediate, and La Romana/San Pedro and Santo Domingo in the south among the least developed. Results are also compared with surveys on visitor satisfaction, perceptions of safety, and propensity to return. Planning and research implications are discussed.     

Preservation or Conversion? Valuation and Evaluation of a Mangrove forest in the Philippines

Mangrove ecosystems are rapidly declining in many parts of the world. This has resulted in the loss of important environmental and economic products and services including forest products, flood mitigation and nursery grounds for fish. The aquaculture industry was the single biggest threat to mangroves in the Philippines until 1981 when conversion of the remaining mangrove stands was prohibited by law. However, the decreasing yield from capture fisheries is putting pressure for the re-examination of this policy. To understand the importance of mangroves, insight is needed into the value of products and services provided is needed. This article compares the costs and benefits of mangrove preservation with those generated by alternative uses such as aquaculture and forestry. Equity and sustainability objectives are taken into account, in addition to economic efficiency and analyzed according to the perspectives of the different types of decision makers involved.     

IS THERE AN ASYMMETRIC BEHAVIOUR IN AFRICAN INFLATION? A NON‐LINEAR APPROACH

In this paper we test the inflation persistence hypothesis as well as model the long‐run behaviour of inflation rates in a pool of African countries using a non‐linear framework. In order to do so, we rely on unit root tests applied to non‐linear models and fractional integration. The results show that the hypothesis of inflation persistence does not hold empirically for most of the countries. In addition, the estimated models (logistic smooth transition autoregressions) are stable in the sense that the variable tends to remain in the regime (low inflation or high inflation) once reached, and changes between regimes are only achieved after a shock. The results also indicate that the effects of the shocks on inflation tend to die out; exogenous factors, i.e. supply shocks and inertia may be causing this outcome, as they play a substantial role in the determination of the inflation rates for our selected African countries.     

Can agency theory justify the regulation of insider trading?

Conclusion The insider trading debate traditionally discusses the pros and cons of insider trading and draws a conclusion about the desirability or undesirability of public regulation of insider trading. One of the most important arguments against insider trading is that it generates agency problems that shareholders cannot resolve and that, therefore, insider trading should be publicly regulated. We have challenged this argument for failing to engage in comparative institutional analysis. We argued that when the negative aspects of insider trading, namely, the agency problems that it may create, are considered, it is necessary to engage in comparative institutional analysis and how these problems can be resolved under two different economic systems: the market economy and interventionism. We have been led to the conclusion that under a market economy, shareholders do have mechanisms to protect themselves against agency problems generated by insider trading and that these problems are reduced to a minimum. We have shown that interventionism hampers the functioning and reduces the disciplinary role of such mechanisms. Therefore, insiders have indeed more latitude to engage in these discretionary behaviors, pointed out by the supporters of the insider-trading-as-an-agency-problem argument, that harm shareholders. Finally, we have shown that the failures of government regulation reinforce this tendency of insiders’ behavior. We conclude that we cannot justify a public regulation of insider trading based on the insider-trading-as-agency-problem argument.
