The effect of minimum wages on employment is a matter of debate, and the existing empirical literature contains mixed results. One reason for this is the methodological difficulties involved where changes in minimum wages are endogenous to other important economic changes. To overcome this problem, we examine exogenous changes to local minimum wages in Indonesia between 1989 and 1994. Our natural experiment results from a national policy change: from minimum wages being determined by local guidelines and criteria to minimum wages being harmonized and set according to nationwide criteria. We examine how these changes in minimum wages affect employment, considering the effect both on employment within plants and on exit of plants. Our results show no evidence of an effect of minimum wages on employment in Indonesian plants. One explanation found in the data is that higher minimum wages force plants to increase productivity, which in turn enables them to retain their labor force, despite higher wage costs.

Offering evidence from both detailed individual country studies and homogenized statistics across the Latin American and Caribbean region, this book examines the impact of the minimum wage on wages, employment, poverty, income distribution and government budgets in the context of a large informal sector and predominantly unskilled workforces.

We show that a dynamic general equilibrium model with efficiency wages and endogenous capital accumulation in both the formal and (non-agricultural) informal sectors can explain the full range of confounding stylized facts associated with minimum wage laws in less developed countries.

This paper provides the first systematic study of how minimum wage policies in China affect firm employment over the 2000-2007 periods. Using a novel dataset of minimum wage regulations across more than 2,800 counties matched with firm-level data, we investigate both the effect of the minimum wage and its policy enforcement tightening in 2004. A dynamic panel (difference GMM) estimator is combined with a “neighbor-pairs-approach” to control for unobservable heterogeneity common to “border counties” that are subject to different minimum wage changes. We show that minimum wage increases have a significant negative impact on employment, with an estimated elasticity of -0.1. Furthermore, we find a heterogeneous effect of the minimum wage on employment which depends on the firm's wage level. Specifically, the minimum wage has a greater negative impact on employment in low-wage firms than in high-wage firms. Our results are robust for different treatment groups, sample attrition correction, and placebo tests.

Belman and Wolfson perform a meta-analysis on scores of published studies on the effects of the minimum wage to determine its impacts on employment, wages, poverty, and more.
