Age-differentiated minimum wages in developing countries

The fact that minimum wages seem especially binding for young workers has led some countries to adopt age-differentiated minimum wages. We develop a dynamic competitive two-sector labor market model where workers with heterogeneous initial skills gain productivity through experience. We compare two equally binding schemes of single and age-differentiated minimum wages, and find that although differentiated minimum wages result in a more equal distribution of income, such a scheme creates a more unequal distribution of wealth by forcing less skilled workers to remain longer in the uncovered sector. We also show that relaxing minimum wage solely for young workers reduces youth unemployment but harms the less skilled ones.     

Growth and poverty in developing countries

Despite the developing countries' impressive aggregate growth of the past 25 years, its benefits have only reached the poor to a very limited degree. Not only have the poorest countries grown relatively slowly, but growth processes are such that within most developing countries, the incomes of the poor increase much less than the average. Although many policies have been proposed to counter these trends, little has been done to estimate the possibilities for significantly reducing world poverty within a reasonable period. This paper develops a quantitative framework to project levels of poverty under different assumptions about GNP growth population growth and changes in income distribution. Although the interactions among development processes and policy instruments are not modelled in any detail, the results serve to clarify the nature of the problem. The policy simulations demonstrate that the elimination of absolute poverty by the end of this century is a highly unlikely prospect; even to achieve a substantial reduction will require a combination of policies designed to accelerate the growth of poor countries, to distribute the benefits of growth more equitably, and to reduce population increase.     

The econometric modelling of aggregate consumer behaviour

This paper examines several problems involved in modelling the structure of consumer behaviour. A new model of consumer demand is presented which encompasses the indirect translog, the CES and the LES as special cases, enabling nested comparisons to be made. Within this framework we show that acceptance of zero-degree homogeneity and/or symmetry of the Slutsky matrix is heavily dependent upon the structure within which inferential tests are carried out, and that great care must be utilised in formulating nested hypotheses and drawing inferences on the basis of χ² and F-statistics. We then show that conventional econometric work implies that consumer preferences must be homothetic if symmetry of the Slutsky matrix is imposed. An alternative procedure is suggested and utilised. Finally, we suggest that low Durbin–Watson statistics may arise from misspecification of functional form and may not be due solely to omitted dynamics, as many conjecture.     

Recent trends in trade among developing countries

The paper presents the early results of empirical work on trade among developing countries. The main conclusion is that non-fuel trade among developing countries, excluding capital surplus oil exporters, remained a remarkably stable share of their total trade between 1963 and 1977. This constancy does, however, conceal two interesting opposing trends: The share of manufactures exported to developing countries has been falling sharply, while that of non-fuel primary commodities has been rising, the latter largely because of the demands of the newly industrializing countries. Nevertheless, the dynamism of manufactures has meant that they make up an increasing share of trade among developing countries. Four particular points emerge from the evidence: (i) there is no obvious sign of a bias against trade among developing countries, except whatever effect their own commercial policies may have; (ii) the more inward-looking countries tend to send a higher proportion of their exports to other developing countries and regional integration strengthens this effect; (iii) exports of manufactures to developing countries are much more capital intensive than those to industrialized countries; and (iv) exports to developing country markets may not be the vital first stage for capital goods exports that is sometimes supposed.     

Decentralizing antipoverty program delivery in developing countries

We study the effects on accountability in government service delivery of decentralizing administration of an antipoverty program. While governments at both central and local levels are vulnerable to antipoor policy biases owing to political capture, centralized delivery systems are additionally prone to bureaucratic corruption, owing to problems in monitoring bureaucratic performance. Decentralizing the delivery system promotes cost-effectiveness and improves intraregional targeting at low program scales. But interregional targeting may deteriorate, as central grants to high-poverty regions shrink, owing to high capture of local governments by local elites in such regions.     

Labor markets and productivity in developing countries

In middle-income countries, the informal sector often accounts for a substantial fraction of the urban labor force. We develop a general equilibrium model with matching frictions in the urban labor market, the possibility of self-employment in the informal sector, and scope for rural–urban migration. We investigate the effects of labor market institutions, different types of growth, and company taxes on labor market outcomes and aggregate productivity. We quantify these effects by calibrating the model to data for Mexico, and show that matching frictions can lead to a large informal sector when formal sector workers have substantial bargaining power.     

Elections and economic policy in developing countries

This paper explores the impact of elections on economic policies and governance in developing countries. We distinguish between a structural effect, which increases accountability, and a cyclical effect which may be disruptive. Since the effects are offsetting, neither can be analysed in isolation. We implement an econometric analysis on more than 80 developing countries using positive changes in the Country Policy and Institutional Assessment of the World Bank and the International Country Risk Guide as signalling improvements in economic policy and governance. We find that both structural and cyclical effects matter. The cyclical effect suggests that mid-term is the best moment for policy change. We investigate the structural effect by comparing different frequencies of elections. Except at the extremes, a higher frequency of elections improves both policy and governance net of any cyclical effect. The important exception to this benign net effect is if the electoral process is badly conducted. Badly conducted elections have no structural efficacy for policy improvement. A reasonable interpretation of our results is that honest elections increase accountability and thereby discipline governments to improve economic policy and governance, but that if candidates can win by fraud this chain is broken.

A note on non-parametric tests of consumer behaviour

This note extends the Afriat-Diewert-Varian conditions for consistency of demand data with the maximization hypothesis to the case where the choice set is a finite union of convex sets. Applications include models with discrete goods, regressive taxes, decreasing block prices and fixed costs.     

Habit,seasonality, and time aggregation in consumer behaviour

Habitual behaviour in consumer demand analysis is generally portrayed via some form of a lagged dependent variable model. The purpose of this paper is to explore the implications for habit behaviour of time aggregation. This is done by specifying both habit and seasonal components in demand relations. The results indicate that much of what has traditionally been identified as habitual behaviour is, in fact, seasonal effects.     

Vertical integration and investor protection in developing countries

The industrial organization of developing countries is characterized by the pervasive use of subcontracting arrangements among small, financially constrained firms. This paper asks whether vertical integration relaxes those financial constraints. It shows that vertical integration trades off the benefits of joint liability against the costs of rendering the supply chain more opaque to external investors. In contrast to the commonly held view that pervasive input and capital market imperfections are conducive to vertical integration, the model predicts that the motives for vertical integration are not necessarily higher in developing countries. In particular, vertical integration is more likely to arise at intermediate levels of investor protection and better contract enforcement with suppliers reduces vertical integration only if financial markets are sufficiently developed. Evidence supporting both predictions is discussed.     

Urban squatting and community organization in developing countries

It is estimated that up to 30–35 percent of the total urban population of the Third World (about 185 million people) live in squatter settlements. This paper presents, from an economic perspective of tenure choice under uncertainty, a unified and consistent theoretical framework of this phenomenon, which has heretofore been studied mainly by other social scientists. The model is able to explain why land invasions occur. Furthermore, it provides some insights as to why the number of squatters in an urban area depends on a squatter community's ability to form coalitions to fully protect its members' rights. It is shown in the paper that, if a community is successful in controlling its size, government efforts which are meant to reduce the number of squatters may lead to the opposite results. In particular, the imposition of heavier fines or the increase of government expenditures on eviction activity (threat campaigns, eviction in other jurisdictions, etc.) will likely lead to an increase in the optimal number of squatters, unless the decline in expected utility caused by these efforts is so great that squatting no longer becomes viable at any community size.     

Fiscal crisis and fiscal reform in developing countries

In recent years, policy-makers in developing countries haveresponded to crisis of macroeconomic instability with two setsof measures: conventional stabilisation policies and policiesof economic liberalisation. The fiscal implications of thisdouble agenda are set out, following three lines of enquiry.First, how can policies be kept consistent, when some liberalisationmeasures have large adverse fiscal consequences? Second, cana fiscal deficit be reduced without damaging the provision ofpublic services vital for growth and poverty alleviation? Finally,since lack of tax revenue is usually the binding constrainton government intervention, how can this most easily be relaxed?     

Integrating business and technology strategies in developing countries

In the present era of deregulation, privatization and increasing global market competition, most industrialists in developing countries have come to the realization that better technology is needed for the survival of both public and private sector enterprises. Therefore, they acknowledge that technological considerations must be properly incorporated into overall business strategies. However, in the absence of an established theory and due to lack of relevant data, they face enormous difficulties. This paper describes a simple framework for integrating business and technology strategies, particularly in the context of developing countries. Possible strategic mixes are identified by considering four commonly practiced business strategies, namely: price, value, niche and image leadership; and four evolving technology strategies, namely: technology leader, follower, exploiter and extender. Necessary considerations for technological capability development and technology strategy progression path are also discussed for different enterprise situations and development conditions.     

Transparency and central bank losses in developing countries

Recent evidence shows central banks suffering from losses in some developing countries. This is a surprise to economists and policymakers. At the same time, these banks are asked to conduct monetary policy within a more transparent framework. Therefore, this paper seeks to answer the following question: Would more transparency in developing countries suffering from central bank losses be beneficial?This paper shows that the cost constraints of conducting monetary policy, central bank losses, in both transparency and opacity alike is significant and affects positively the error of the private sector in expected inflation rate and the output gap. In a country suffering from central bank losses, the expected benefits of transparency and the existence of cost constraint move in two opposite directions. As a result, it is unwise for developing countries suffering from central bank losses to focus on transparency. Priority should be given to fixing monetary policy and to developing financial markets.     

On selective indirect tax reform in developing countries

The current consensus on indirect tax reform in developing countries favors a reduction in trade taxes with an increase in VAT to raise revenue. The theoretical results on selective reform that underlie this consensus are, however, derived from partial models that ignore the existence of an informal economy. Once the incomplete coverage of VAT due to an informal economy is acknowledged, we show that, contrary to the current consensus, the standard revenue-neutral selective reform of trade taxes and VAT reduces welfare under plausible conditions. Moreover, a VAT base broadening with a revenue-neutral reduction in trade taxes may also reduce welfare. The results raise serious doubts about the wisdom of the indirect tax reform policies pursued by a large number of developing countries.     

Religiosity,income and wellbeing in developing countries

This study examines the relationship between religiosity, income and subjective wellbeing in a sample of developing countries using data from the World Values Survey Waves 2–6 (1990–2014). Beyond examining the effects of religiosity and income on subjective wellbeing separately and independently, we also examine how the interaction between religiosity and income affects wellbeing. Our results suggest that while both religiosity and income positively affect wellbeing, the effect of income on wellbeing is relatively stronger (quantitatively larger in size) than the effects of religiosity. Furthermore, we find evidence in favour of complementarity between religiosity and income which show stronger effects on wellbeing than the individual effects of income and religiosity.

     

An assessment of telecommunications reform in developing countries

This paper analyzes the impact of policy reform in basic telecommunications on sectoral performance using a new panel data set for 86 developing countries across Africa, Asia, the Middle East, Latin America and the Caribbean over the period 1985 to 1999. We address three questions. First, what impact do specific policy changes—relating to ownership and competition—have on sectoral performance? Second, how is the impact of change in any one policy affected by the implementation of the other, and by the overall regulatory framework? Third, does the sequence in which reforms are implemented affect performance? We find that both privatization and competition lead to significant improvements in performance. But a comprehensive reform program, involving both policies and the support of an independent regulator, produced the largest gains: an 8 percent higher level of mainlines and a 21 percent higher level of labor productivity compared to years of partial and no reform. Interestingly, the sequence of reform matters: mainline penetration is lower if competition is introduced after privatization, rather than at the same time.
