The Finance–Growth Link in Latin America

This paper analyzes the relationship between financial development and economic growth in Latin America with a Granger causality test and impulse response functions in a panel vector autoregression (VAR) model. With annual observations from a sample of 18 countries from 1962 to 2005, it is shown that while economic growth causes financial development, financial development does not cause economic growth. This finding is robust to different model specifications and different financial indicators. Interestingly, when the sample is divided according to different income levels and institutional quality, there is two‐way causality between financial development and economic growth only for the middle income group and for countries with stronger rule of law and creditor rights. The impulse response functions show that a shock to financial development has a positive impact on economic growth only for these subsamples, but the net effect of financial development on growth is relatively small.     

State dependence and unobserved heterogeneity in the employment transitions of the over-50s

This paper examines employment transitions among men and women in the UK aged between 50 and the state pension age. We use a fourth order Markov model to estimate quarterly transitions while allowing for potential endogeneity of initial conditions. The results reject exogeneity of initial conditions and show the importance of state dependence. We compare the results to those obtained with a younger sample and find evidence of a sorting process over the life-cycle whereby men’s employment transitions are increasingly characterized by state dependence while, for women, unobserved heterogeneity becomes more important. We discuss some potential policy implications of the results.     

Economic burden of hospital malnutrition and the cost–benefit of supplemental parenteral nutrition in critically ill patients in Latin America

Abstract

Aim: Disease-related malnutrition (DRM) is a prevalent condition that significantly increases the risk of adverse outcomes in hospitalized patients, particularly those with critical illness. Limited data is available on the economic burden of DRM and the cost–benefit of nutrition therapy in high-risk populations in Latin America. The aims of the present study were to estimate the economic burden of DRM and evaluate the cost–benefit of supplemental parenteral nutrition (SPN) in critically ill patients who fail to receive adequate nutrient intake from enteral nutrition (EN) in Latin America.

Methods: Country-specific cost and prevalence data from eight Latin American countries and clinical data from studies evaluating outcomes in patients with DRM were used to estimate the costs associated with DRM in public hospitals. A deterministic decision model based on clinical outcomes from a randomized controlled study and country-specific cost data were developed to examine the cost–benefit of administering SPN to critically ill adults who fail to reach ≥60% of the calculated energy target with EN.

Results: The estimated annual economic burden of DRM in public hospitals in Latin America is $10.19 billion (range, $8.44 billion–$11.72 billion). Critically ill patients account for a disproportionate share of the costs, with a 6.5-fold higher average cost per patient compared with those in the ward ($5488.35 vs. $839.76). Model-derived estimates for clinical outcomes and resource utilization showed that administration of SPN to critically ill patients who fail to receive the targeted energy delivery with EN would result in an annual cost reduction of $10.2 million compared with continued administration of EN alone.

Limitations: The cost calculation was limited to the average daily cost of stay and antibiotic use. The costs associated with other common complications of DRM, such as prolonged duration of mechanical ventilation or more frequent readmission, are unknown.

Conclusions: DRM imposes a substantial economic burden on Latin American countries, with critically ill patients accounting for a disproportionate share of costs. Cost–benefit analysis suggests that both improved clinical outcomes and significant cost savings can be achieved through the adoption of SPN as a therapeutic strategy in critically ill patients who fail to receive adequate nutrient intake from EN.     

Estimating liquidity premia in the Spanish government securities market

This paper investigates the presence of liquidity premia in the relative pricing of assets traded on the Spanish government securities market. First, a classification of bonds into four different categories based on their degree of liquidity is proposed. Second, liquidity premia are estimated introducing liquidity parameters in the estimation of the zero-coupon yield curve. Results suggest the existence of a liquidity premium for post-benchmark bonds (both strippable and non-strippable). The size of this premium is relatively small. In the case of pre-benchmark bonds, the lack of liquidity does not seem to be priced. It is also shown that these pricing discrepancies are robust to the impact of taxes on bonds.     

Mixed tempered stable distribution

In this paper, we introduce a new parametric distribution, the mixed tempered stable. It has the same structure of the normal variance–mean mixtures but the normality assumption gives way to a semi-heavy tailed distribution. We show that, by choosing appropriately the parameters of the distribution and under the concrete specification of the mixing random variable, it is possible to obtain some well-known distributions as special cases. We employ the mixed tempered stable distribution which has many attractive features for modelling univariate returns. Our results suggest that it is flexible enough to accommodate different density shapes. Furthermore, the analysis applied to statistical time series shows that our approach provides a better fit than competing distributions that are common in the practice of finance.     

Early Evolution of the Assumption of Non-satiation

The paper explores the mostly tacit transmission of the assumption of non-satiation from the outset of classical political economy to the advent of marginal analysis in Great Britain. The evolution of the assumption is traced back to contributions to the philosophy of mind in the early British enlightenment, which provided scientific ground not only to the economic agent's insatiable nature but also to a delusional dynamic of association that challenges the causality between acquisitiveness and pleasure. The paper claims that, because there is evidence that such delusional aspect was known to the early political economists, the assumption of non-satiation might have become a mainstay in economics not only for its scientific status but also as a result of a strategic choice that can only be explained within the political, cultural, and social context in which it was made. Had this been the case, the exportability of the assumption through time and space must be further questioned. The consistent inclusion of non-satiation in economic theories, policies, and institutions may have had extraordinary consequences, and may have nurtured rational behaviors that in fact fulfill the assumption itself.     

Does the WTO Increase Trade and Cause Convergence?

We study whether proximity to the nearest tax haven affects FDI and the number of American affiliates in a tax haven. Our results show that distance to the nearest tax haven is positively related to FDI inflows and the number of American affiliates in tax havens. These findings suggest that there is harmful competition between tax havens. We also find evidence of positive spillovers: the number of American affiliates in a tax haven is positively related to the number of affiliates in its closest neighboring tax haven. This suggests the presence of agglomeration benefits given there is an affiliate in a nearby tax haven.     

The effect of violent crime on sector-specific FDI in Latin America

ABSTRACT

This article looks at the impact of violent crime on FDI into Latin America and the Caribbean during the 1996–2010 period. FDI is disaggregated into primary, secondary and tertiary sectors and three variables related to violent crime are used: homicides, crime victimization and organized crime. Controlling for institutions and the traditional determinants of FDI, we find that the impact of crime on FDI depends on the sector and types of crime considered. Higher homicide rates are associated with less FDI in the secondary sector while organized crime reduces tertiary sector FDI. Crime victimization has a robust significant negative impact on the tertiary sector and in some estimations of the secondary sector. Crime has no impact on primary sector FDI. Our study highlights the need to continue efforts to decrease crime as we show in our analysis that crime has a negative effect on FDI in the secondary and tertiary sector.     

Estimates of foreign exchange risk premia: a pricing kernel approach

The goal of this study is to measure market prices of risk and foreign exchange risk premia. Estimations of minimum variance pricing kernels permit to determine market prices of risk, which, in an international no-arbitrage framework, allow to measure foreign exchange risk premia. Market prices of risk are time-varying and surge during financial turmoils. Foreign exchange risk premia are on average small in comparison to interest rate differentials and exhibit significant variation from the early 1970s onwards, when the Bretton Woods exchange rate system collapsed. At times, foreign exchange risk premia dominate interest rate differentials.
