The convergence features of an Endogenous Growth model with Physical capital, Human Capital and R&D have been studied. We add an erosion effect (supported by empirical evidence) to this model, and fully characterize its convergence properties. The dynamics is described by a fourth-order system of differential equations. We show that the model converges along a one-dimensional stable manifold an...

When it comes to the inequality-growth relationship, the empirical literature offers contradictory assessments: Estimators based on time-series variation only (i.e., differencesbased estimators) indicate a strong positive link while estimators also exploiting the crosssectional variation (i.e., level-based estimators) suggest a negative relationship. Taking advantage of a new dataset, the prese...

The “middle-income trap” is the phenomenon of hitherto rapidly growing economies stagnating at middle-income levels and failing to graduate into the ranks of high-income countries. In this study we examine the middle-income trap as a special case of growth slowdowns, which are identified as large sudden and sustained deviations from the growth path predicted by a basic conditional convergence f...

In this paper, we investigate the determinants of political instability in Latin America. In a panel of 18 Latin American countries from 1971 to 2000, we find that democratic countries experience less average instability in the region, indicating that the move to increased democracy in the last couple decades may alleviate the persistent problem of instability in the area. We also find that inc...

Whether or not the marginal product of capital (MPK) differs across countries is a question that keeps coming up in discussions of comparative economic development and patterns of capital flows. Using easily accessible macroeconomic data we find that MPKs are remarkably similar across countries. Hence, there is no prima facie support for the view that international credit frictions play a major...

Macro-level estimates of the productivity of public capital are typically larger than microlevel estimates. The evidence also shows large cross-country differences in the quality of public capital. A general equilibrium growth model is introduced to explain both facts. The productivity of firms specializing in differentiated intermediate inputs depends on public capital whose provision is subje...

This paper uses the adaptive Lasso estimator to determine variables important for economic growth. The adaptive Lasso estimator is a computationally very efficient procedure that simultaneously performs model selection and parameter estimation. The computational cost of this method is negligibly small compared with standard approaches in the growth regressions literature. We apply this method f...

A collection of 63 isolates of Pseudomonas aeruginosa associated with ulcerative keratitis, collected from six centres in England, were typed using serotyping and random amplified polymorphic DNA-PCR, and screened for several variable virulence-related genotypes and phenotypes. Sixty-one percent of the isolates were of either serotype O1 or serotype O11, but there was no evidence for a common c...

Two traditional explanations for structural changes are sector-biased technological progress and non-homothetic preferences. This paper integrates both into an otherwise standard growth model and quantitatively evaluates them vis-a-vis time series. The exercise identifies a set of puzzles for standard theories: (i) the model cannot account for the steep decline in manufacturing and rise in serv...
