The standard of living in Latin America during the twentieth century1

New and consistent series for Latin American real incomes, life expectancy and adult literacy over the twentieth century reveal that living standards rose most rapidly between the 1930s and 1970s, a period characterised by increased state intervention and reduced trade openness. Within the region, Brazil and Mexico advanced most over the century as a whole despite the early start made by Argentina and Chile, although convergence between larger countries was accompanied by divergence from smaller ones. There was no sustained narrowing of the income gap with the US at all between 1900 and 2000 but some convergence in living standards due to improved life expectancy. Our new estimates of regional per capita income also permit a clearer comparison with both Europe and Asia. The major advances in living standards achieved in the middle decades of the century were closely related to early industrialization, rapid urbanization, and the extension of primary health and education. Subsequent economic volatility and fiscal fragility limited further increases in living standards, undermining social consensus on development strategy.     

PRODUCTIVITY GROWTH IN LATIN AMERICA OVER THE LONG RUN

The low pace of Latin American productivity growth in recent decades, despite extensive economic reforms, has yet to be understood in a longer‐run context where factors such as demographic changes, structural shifts, and investment levels can be taken fully into account. The OxLAD database provides comparable sectoral output and workforce series over 1900–2000 for the six leading economies in the region for the first time. Our analysis of this new dataset shows that: intersectoral resource reallocation reduced aggregate productivity growth in all three periods; total factor productivity growth was low throughout the century, and even negative in the closing three decades; and thus factor accumulation—investment in fixed capital and skilled labor—was the main source of productivity growth in Latin America during the twentieth century.     

SERVICE QUALITY IN REGULATED NETWORK INDUSTRIES

ABSTRACT ** : Economic regulators provide incentives for good quality of service as well as constraints on the prices or revenue which can be charged by firms with monopoly power. Economic theory suggests that regulators should choose standards according to consumers' valuation and the marginal cost of quality improvements, and that firms respond by equalizing the marginal costs from not making improvements (i.e. the regulatory penalty plus any loss in revenue) with the marginal costs of improvement. This paper explores the evidence for such economically rational behaviour by both regulators and regulatees. We use a specially constructed data set on service quality targets and achievements across the main UK utility sectors; documentary evidence from regulators; and interviews with managers in companies subject to those regulators. We conclude that regulators are motivated by political as well as economic factors. And that companies may not respond primarily to the regulator's financial rewards or penalties for their quality targets, with a consequent danger that regulated consumers pay for marketing in unregulated markets; the resulting level of service quality may be ‘too high’ in the economic sense.
