Several recent critiques have questioned the theoretical logic of standard models of balance-of-payments-constrained growth (BPCG) and the empirical support for 'Thirlwall's law'. On the empirical side, critics charge that most econometric estimates of this model have effectively only tested whether exports and imports grow at similar rates in the long run. On the theoretical side, the criticisms have focused on the role of foreign income growth, capital accumulation, relative prices and country size in BPCG models. This article reviews the current state of the debate over these critiques and also offers a brief discussion and evaluation of three alternative models. The alternative models all highlight a significant role for the level of relative prices (or the real exchange rate) in determining long-run growth, which is consistent with recent empirical studies.

The paper presents two short-run, structuralist models of an export-oriented, two-sector, semi-industrialized economy in which women workers are concentrated in export production. The first model analyzes the comparative static effects of an exogenous increase in female wages holding male wages and the exchange rate constant. The second model endogenizes the female-male wage ratio and the real exchange rate, assuming flexible nominal wages and a crawling-peg exchange rate. Either stable or unstable dynamics are possible. In the stable cases, a depreciation policy can either close or widen the gender wage gap.

Previous studies have found that a tightening of the balance of payments (BP) constraint can explain the slowdown in Mexico's growth after its trade liberalization in the late 1980s. This paper develops a disaggregated model of the BP constraint with two types of exports (manufactured and primary commodities) and two types of imports (intermediate and final goods). Econometric estimates (including tests for structural breaks) show that the BPequilibrium growth rate did not fall, but instead rose in the post-liberalization period, so this model cannot account for the country's growth slowdown. Instead, the analysis points to the need to consider the real exchange rate as well as internal obstacles and policies.

This paper estimates a structural model of the balance of payments, with disaggregated exports (manufactures and other) and imports (final and intermediate), and a reduced form model of the trade balance for the Mexican economy. The analysis identifies structural changes in the composition of Mexico's trade and the parameters that affect it across five subperiods marked by statistical breakpoints. The results indicate that a tightening of the balance-of-payments constraint may account for the post-liberalization slowdown in Mexico's growth only during certain subperiods, and that the impact of real exchange rate changes on the trade balance has diminished, most likely as a result of the increasing integration of export industries into global supply chains. The results also suggest an asymmetry, whereby a country cannot sustain growth above the rate consistent with balance-of-payments equilibrium, as expected, but it can grow persistently below that rate when other constraints are more binding.

ABSTRACT

This paper finds that shocks to net financial inflows, world oil prices, the U.S. growth rate, and the lagged real exchange rate explain most of the fluctuations in Mexico's annual growth since 1979. The paper also estimates how the effects of these external constraints have changed since Mexico's liberalization policies of the late 1980s and the formation of NAFTA in 1994. Estimates of an investment function and other tests show that growth drives investment but not conversely, in the short run. Investment is driven mainly by oil prices and the accelerator effect; foreign direct investment has no significant impact.
