Self-Help Groups and Income Generation in the Informal Settlements of Nairobi

The aim of this paper is to understand the functioning and the scope of self-help groups in the informal settlements of urban areas as a means of generating income for poor households. The paper uses a unique dataset collected by the author in 1999 surveying all individual group members from several informal settlements of Nairobi. It studies the individual determinants of earnings within groups and relates group composition to various indicators of group functioning. Sex, age and ethnic identity are among the most important determinants of individual reliance on group income and of access to group loans. Heterogeneity in earnings among members is shown to reduce their ability to borrow from the group as a whole but not from each other. The impact of ethnic and other forms of heterogeneity on the division of labor, choice of compensation schemes, sanctioning technology and recruitment criteria is also described.self-help groups, cooperative, participation, social capital

Participation in Heterogeneous Communities

This paper studies both theoretically and empirically the determinants of group formation and of the degree of participation when the population is heterogeneous, both in terms of income and race or ethnicity. We are especially interested in whether and how much the degree of heterogeneity in communities influences the amount of participation in different types of groups. Using survey data on group membership and data on US localities, we find that, after controlling for many individual characteristics, participation in social activities is significantly lower in more unequal and in more racially or ethnically fragmented localities. We also find that those individuals who express views against racial mixing are less prone to participate in the groups the more racially heterogeneous their community is.

Ethnic Diversity and Economic Performance

We survey and assess the literature on the positive and negative effects of ethnic diversity on economic policies and outcomes. Our focus is on both focus both cities in developed countries (the US) and villages in developing countries. We also consider the endogenous formation of political jurisdictions and we highlight several open issues in need of further research.

The Determinants of Trust

Both individual experiences and community characteristics influence how much people trust each other. Using data drawn from US localities we find that the strongest factors that reduce trust are: i) a recent history of traumatic experiences, even though the passage of time reduces this effect fairly rapidly; ii) belonging to a group that historically felt discriminated against, such as minorities (black in particular) and, to a lesser extent, women; iii) being economically unsuccessful in terms of income and education; iv) living in a racially mixed community and/or in one with a high degree of income disparity. Religious beliefs and ethnic origins do not significantly affect trust. The latter result may be an indication that the American melting pot at least up to a point works, in terms of homogenizing attitudes of different cultures, even though racial cleavages leading to low trust are still quite high.

Television and Divorce: Evidence from Brazilian Novelas

This paper studies the link between television and divorce in Brazil by exploiting variation in the timing of availability of the signal of Rede Globo—the network that had a virtual monopoly on telenovelas in the country—across municipal areas. Using three rounds of Census data (1970, 1980 and 1991) and controlling for area fixed effects and for time-varying characteristics, the paper finds that the share of women who are separated or divorced increases significantly after the Globo signal becomes available. The effect is robust to controlling for potential determinants of Globo’s entry strategy and is stronger for relatively smaller areas, where the signal reaches a higher fraction of the population.Divorce, Television, Brazil, Soap Operas, Media, Women, Empowerment

The economic effects of violent conflict: evidence from asset market reactions

This paper studies the effects of conflict onset on asset markets applying the event study methodology. We consider a sample of 112 conflicts during the period 1974-2004 and find that a sizeable fraction of them had a significant impact on stock market indices and on major commodity prices. Furthermore, our results suggest that we are more likely to see investor reactions in response to conflicts that occur in highly polarized settings, possibly because the expected duration and intensity of the conflict is higher.Stock exchanges ; Prices

Diamonds are forever, wars are not. Is conflict bad for private firms?

This paper studies the relationship between civil war and the value of firms in a poor, resource abundant country using microeconomic data for Angola. We focus on diamond mining firms and conduct an event study on the sudden end of the conflict, marked by the death of the rebel movement leader in 2002. We find that the stock market perceived this event as “bad news” rather than “good news” for companies holding concessions in Angola, as their abnormal returns declined by 4 percentage points. The event had no effect on a control portfolio of otherwise similar diamond mining companies. This finding is corroborated by other events and by the adoption of alternative methodologies. We interpret our findings in the light of conflict-generated entry barriers, government bargaining power and transparency in the licensing process.Microeconomics ; Mineral industries

Detecting Illegal Arms Trade

Illegal arms are responsible for thousands of deaths in civil wars every year. Yet, their trade is very hard to detect. We propose a method to statistically detect illegal arms trade based on the investor knowledge embedded in financial markets. We focus on eight countries under UN arms embargo in the period 1990-2005, and analyze eighteen events during the embargo that suddenly increase or decrease conflict intensity. If the weapon-making companies are not trading or are trading legally, an event worsening the hostilities should not affect their stock prices or affect them adversely, since it delays the removal of the embargo. Conversely, if the companies are trading illegally, the event may increase stock prices, since it increases the demand for illegal weapons. We detect no significant effect overall. However, we find a large and significant positive reaction for companies head-quartered in countries where the legal and reputation costs of illegal trades are likely to be lower. We identify such countries using measures of corruption and transparency in arms trade. We also suggest a method to detect potential embargo violations based on stock reactions by individual companies, including chains of reactions. The presumed violations are higher for conflicts with more UN investigations and for companies with more Internet stories regarding embargo.

Fighting poverty with soap operas

With their tremendous reach and popularity, soap operas might at first look like light entertainment but they are a potentially potent tool to influence attitudes and spur growth and developmen
