The structure of labor markets in developing countries : time series evidence on competing views

Listed author(s):
  • Maloney, William F.

Competing conceptions of the large, unprotected,"informal"workforce in developing countries differ greatly in their implications for the labor reform considered to be essential complements to trade liberalization and"fair"competition in international trade. Traditionally, the informal sector is viewed as the disadvantaged segment of a dual labor market segmented by legislated or union-induced rigidities and high labor costs in the protected (or"informal") sector. In this view, the size of the informal sector is a testament to the inefficiencies in labor allocation and the magnitude of required reform. In cyclical downturns, the informal sector is thought to absorb displaced workers from the formal sector (with informal earnings falling relative to those in the formal sector) and then to contract again during recovery as the queue for"good jobs"shortens again. A recent, related view postulates a long-term trend in which large enterprises, confronted by heightened global competition, increasingly subcontract to unprotected workers as a way to reduce costs and gain flexibility. This is particularly relevant in the debate about establishing common labor standards in regional trade agreements. The author reexamines the traditional view of the dual labor market by studying the dynamics between the formal and informal sectors across a business cycle and a period of trade liberalization in Mexico (1987-93). He shows conventional comparisions of earnings, even across time, to be unreliable tests for segmentation. As an alternative, he shows that transitions on informal employment, the size of the informal sector, and levels of mobility to be procyclical, increasing with upturns, and decreasing with recessions. He tests for, and finds, however, some evidence of queuing to enter formal employment. Overall, he contends, the informal sector behaves as an unregulated entrepreneurial sector rather than the disadvantaged wing of a dual labor market. There is evidence of increased subcontracting over time, with trade liberalization, but it is not clear that workers are worse off as a result.
