The Impact of Labor Market Regulation on Employment in Low‐Income Countries: A Meta‐Analysis

Controversy over labor market policy often centers on achieving a balance between preventing worker exploitation, and avoiding loss of productivity or employment through excessive regulation. Although the literature documenting the impact of labor market regulation on employment is extensive, there is a dearth of evidence on the impact of such policies in low-income countries (LICs). Since it is easier for workers, especially women, to slip into the informal sector in LICs, regulations are likely to have stronger impacts on formal employment in these countries (but lower impacts on unemployment). We systematically reviewed available research from countries that are, or were until recently, LICs. Most studies document that more stringent labor regulations are associated with lower formal sector employment and higher informal sector employment. We also conducted a metaregression analysis of the impact of minimum wages on formal and informal employment. After controlling for publication bias, higher minimum wages are associated with lower formal employment and a higher share of informal workers.

Economic analysis of complementary, alternative, and integrative medicine: considerations raised by an expert panel

BackgroundAn international panel of experts was convened to examine the challenges faced in conducting economic analyses of Complementary, Alternative and Integrative Medicine (CAIM).MethodsA one and a half-day panel of experts was convened in early 2011 to discuss what was needed to bring about robust economic analysis of CAIM. The goals of the expert panel were to review the current state of the science of economic evaluations in health, and to discuss the issues involved in applying these methods to CAIM, recognizing its unique characteristics. The panel proceedings were audiotaped and a thematic analysis was conducted independently by two researchers. The results were then discussed and differences resolved. This manuscript summarizes the discussions held by the panel members on each theme.ResultsThe panel identified seven major themes regarding economic evaluation that are particularly salient to determining the economics of CAIM: standardization (in order to compare CAIM with conventional therapies, the same basic economic evaluation methods and framework must be used); identifying the question being asked, the audience targeted for the results and whose perspective is being used (e.g., the patient perspective is especially relevant to CAIM because of the high level of self-referral and out-of-pocket payment); the analytic methods to be used (e.g., the importance of treatment description and fidelity); the outcomes to be measured (e.g., it is important to consider a broad range of outcomes, particularly for CAIM therapies, which often treat the whole person rather than a specific symptom or disease); costs (e.g., again because of treating the whole person, the impact of CAIM on overall healthcare costs, rather than only disease-specific costs, should be measured); implementation (e.g., highlighting studies where CAIM allows cost savings may help offset its image as an “add on” cost); and generalizability (e.g., proper reporting can enable study results to be useful beyond the study sample).ConclusionsThe business case for CAIM depends on economic analysis and standard methods for conducting such economic evaluations exist. The challenge for CAIM lies in appropriately applying these methods. The deliberations of this panel provide a list of factors to be considered in meeting that challenge.

When Do Firms Go Green? Comparing Price Incentives with Command and Control Regulations in India

There are two commonly accepted views about command-and-control (CAC) environmental regulation. First, CAC delivers environmental outcomes at very high cost. Second, in a developing country with weak regulatory institutions, CACs may not even yield environmental benefits: regulators can force firms to install pollution abatement equipment, but cannot ensure that they use it. We examine Indias experience and find evidence that CAC policies achieved substantial environmental benefits at a relatively low cost. Constructing an establishment-level panel from 1998 to 2009, we find that the CAC regulations imposed by Indias Supreme Court on 17 cities improved air quality with little effect on establishment productivity. We document a strong effect of deterred entry of high-polluting industries into regulated cities; however little effect on the overall level of manufacturing output, employment, or productivity in those cities. We also find sustained reductions in within-establishment coal use, with no evidence of leakage into other fuels. To benchmark our results, we use variation in coal prices to compare the CAC policies to price incentives. We show that CAC regulations were primarily effective at reducing coal consumption of large urban polluters, while a coal tax is likely to have a broader impact across all establishment types. Our estimated coal price elasticity suggests that a 15-30% excise tax would be needed to generate reductions in coal consumption equivalent to those produced by these CAC policies.

What is the Impact of Labour Market Regulation on Employment in LICs? How Does it Vary by Gender?

There is an extensive empirical literature examining the impacts of various labour market regulations on employment outcomes. However, much of this evidence focuses on developed or middle-income countries, resulting in a comparative dearth of literature that analyzes the impact of such policies in low-income countries (LICs). In addition, there are few studies that examine the impacts of such regulations by gender. This systematic review aims to synthesize the literature by focusing on the impact of labour market regulation on employment in LICs and how it varies by gender.

Does Informal Employment Respond to Growth Opportunities? Trade-Based Evidence from Bangladesh

Informal employment accounts for the majority of employment in many developing countries, yet its relevance to growth, and its links with the formal sector, remain poorly understood. A widely held view is that informality eventually gives way to formality as countries develop. In this paper, we examine the effects of growth opportunities — in the form of export-induced demand in Bangladesh — on four types of employment: formal, casual, unpaid, and self-employment. At an aggregate level, export-induced demand increases the levels of all four types of employment. We also conduct a district-level analysis, constructing a shift-share measure of trade exposure that relies on national, industry-level variation in exports, coupled with pre-existing, district-level shares of employment by industry. We find that the direct impact of trade is to increase labor force participation and formal employment. When we also include the indirect impacts of trade, in the form of induced demand through supply chain linkages, we find an even larger impact on labor force participation. The results also suggest that trade triggers an immediate increase in both formal and casual employment, as well as a longer-run increase in self-employment. We conclude that labor response to growth opportunities such as trade is not limited to formal employment, and a more nuanced understanding of informality in the growth process is needed.

Assessing the Spatial Concentration of Indonesia's Manufacturing Sector: Evidence from Three Decades

Beyond the role of economic forces, many theories of economic geography emphasize the way politics can shape the spacial configuration of economic activity. We investigate the impact of changes in political regimes on industrial concentration using 30 years of data on Indonesian manufacturers. These data span both the reign of Suharto, one of the strongest central governments in Southeast Asia, and its collapse and the subsequent decentralization of power. Using the canonical measure of Ellison and Glaeser, we show that in the mid 1980s, Indonesias firms exhibited a similar degree of agglomeration as seen in the United States. Spatial concentration then declined until the 1998 Asian Financial Crisis, and has since begun to rise during the decentralization period. We also measure concentration using the continuous measure developed by Duranton and Overman (2005), and find that the agglomeration exhibited by Indonesian firms is also broadly similar to that documented by Duranton and Overman (2005 ) for the United Kingdom, although localization drops off more gradually in Indonesia than in the United Kingdom. Using this continuous measure of agglomeration, we identify 32 manufacturing clusters in Indonesia, and investigate the correlates of concentration. We find that the most robust drivers of agglomeration have been natural resources and supply chain linkages, especially with respect to explaining long-term changes in spatial concentration.
