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

The aim of this paper is to understand the functioning and thescope of self-help groups in the informal settlements of urbanareas as a means of generating income for poor households. Ituses a unique data set collected by the author in 1999 surveyingall individual group members from several informal settlementsin Nairobi. It studies the individual determinants of earningswithin groups and relates group composition to various indicatorsof group functioning. Sex, age and ethnic identity are amongthe most important determinants of individual reliance on groupincome and of access to group loans. Heterogeneity in earningsamong members is shown to reduce their ability to borrow fromthe group as a whole but not from each other. The impact ofethnic and other forms of heterogeneity on the division of labour,choice of compensation schemes, sanctioning technology and recruitmentcriteria is also described.     

Political Competition in Weak States

In the developing areas, politics is often undemocratic, states lack a monopoly over violence, and politicians play upon cultural identities. To analyze politics in such settings, we develop a model in which politicians compete to build a revenue yielding constituency. Citizens occupy fixed locations and politicians seek to maximize rents. To secure revenues, politicians must incur the costs of providing local public goods and mobilizing security services. Citizens must participate, i.e. pay taxes; but can choose which leader to support. The model enables us to explore the impact of cultural identities and varying notions of military power.     

Systemic financial risk indicators and securitised assets: an agent-based framework

The paper presents an agent-based model of a credit economy which includes a securitisation process and a bailout mechanism for bank bankruptcies. Within this framework, banks are able to sell mortgages to a financial vehicle corporation, which finances its activity by creating mortgage-backed securities and selling them to a mutual fund. In turn, the mutual fund collects liquidity by selling shares to households and remunerates them with a monthly interest. The impact of this mechanism is analysed by means of computational experiments for different levels of banks’ securitisation propensity. Furthermore, we study a set of systemic risk indicators which have the aim of assessing the imbalances in the financial system. Two of them are the mortgage-to-GDP ratio and the capital adequacy ratio, which are constructed to detect only the on-balance sheet changes in banks’ credit exposure. We consider two additional indicators, similar to the previous ones with the only difference that they are also able to account for the off-balance sheet items. Moreover, we adopt an indicator, the so-called “virtuous–unvirtuous cycle” indicator, which, besides off-balance assets, targets also the GDP. The results show that higher securitisation propensity weakens the financial stability of banks with relevant effects on different sectors of the economy. Most importantly, the analysis of systemic risk reveals the important issue of designing suitable systemic risk indicators for predicting incoming financial crises, finding that an essential feature of these indicators should be to integrate banks’ off-balance sheet assets.

     

Decomposition of gender differentials in agricultural productivity in Ethiopia

A number of studies document gender differentials in agricultural productivity. However, they are limited to region and crop‐specific estimates of the mean gender gap. This article improves on previous work in three ways. First, data representative at the national level and for a wide variety of crops is exploited. Second, decomposition methods—traditionally used in the analysis of wage gender gaps—are employed. Third, heterogeneous effects by women's marital status and along the productivity distribution are analyzed. Drawing on data from the 2011–2012 Ethiopian Rural Socioeconomic Survey, we find an overall 23.4 percentage point productivity differential in favor of men, of which 13.5 percentage points (57%) remain unexplained after accounting for gender differences in land manager characteristics, land attributes, and access to resources. The magnitude of the unexplained fraction is large relative to prior estimates in the literature. A more detailed analysis suggests that differences in the returns to extension services, land certification, land extension, and product diversification may contribute to the unexplained fraction. Moreover, the productivity gap is mostly driven by non‐married female managers—particularly divorced women—; married female managers do not display a disadvantage. Finally, overall and unexplained gender differentials are more pronounced at mid‐levels of productivity.     

Descent rules and strategic transfers. Evidence from matrilineal groups in Ghana

Traditional descent systems can roughly be divided into patrilineal and matrilineal. In the latter, a man's heir is not his own child but rather his sister's son. The paper examines the implications of this social norm for the pattern of inter-vivos transfers using household level data from rural Ghana, where the largest ethnic group is traditionally matrilineal. In particular, it tests the predictions of a model of strategic behavior according to which children should respond to the threat of disinheritance by increasing transfers to their parents during lifetime to induce a donation of land before the default (matrilineal) inheritance is enforced. I find that the credibility of customary norms enforcement, as proxied by the presence of a nephew in the father's household, significantly increases the probability of receiving transfers from children for Akans but not for the other groups. The effect is specific to nephews and not to other co-resident boys. This pattern of behavior can affect asset accumulation decisions across generations.     

Trade Specialization in Latin America: The Impact of China and India

This paper examines the extent to which the growth of China and India in world markets is affecting the patterns of trade specialization in Latin American (LA) economies. We construct a measure of Revealed Comparative Advantage (RCA) by 3-digit ISIC sector, country, and year. This RCA accounts for both imports and exports. The empirical analyses explore the correlation between the RCAs of LA and the two Asian economies. Econometric estimates suggest that the specialization pattern of LA—with the exception of Mexico—has been moving in opposite direction to the trade specialization pattern of China and India. Labor-intensive sectors (both unskilled and skilled) probably have been negatively affected by the growing presence of China and India in world markets, while natural resource and scientific knowledge intensive sectors have probably benefited from China and India’s growth since 1990.

Minidevaluations and indexed wages: The Brazilian experience in the seventies

This paper examines how financing a deficit in the trade balance permitted Brazil to increase her productive capacity during the last decade. The model presented brings into the center of the argument the question of the division of output between the classes of society stressing the political element in economic development. It incorporates indexed wages and their interplay with minidevaluations together with the effects these policies had on growth, inflation and the functional distribution of income, during the last decade. The persistent surplus of imports has led to debt payments that already put a burden on the balance of payments. Policies available for adjusting the Brazil foreign accounts are discussed.     

Entry regulations and labour market outcomes: Evidence from the Italian retail trade sector

The paper analyzes the relationship between entry regulations and employment in the Italian retail trade sector. In Italy the opening of large outlets is regulated at the regional level. First, by using differences-in-differences estimators the paper presents evidence that in regions with less stringent entry regulations, retail trade employment does not decrease. Second, the paper focuses on the effects of the rules implemented in Abruzzo and Marche, two otherwise close and similar Italian regions which adopted very different policies: the first set tight restrictions on the opening of large stores; the second did not impose substantial entry regulations. The results show that in Marche after the inception of the flexible regulations the share of total retail trade employment in total population increased by 0.8 percentage points more than in Abruzzo. Fiercer competition also led to a recomposition of employment in small retail shops. These findings are robust to a number of checks.
