The Validity of Gibrat’s Law: Evidence from Ecuadorian Service SMEs

The objective of this research is to analyze the relationship between size and growth through the validation of Gibrat's law. A sample of 17,082 Ecuadorian companies in the service sector is used for the period 2010–2015. The estimation method used is that of quantile regression for panel data; the results suggest that small companies grow faster than their larger counterparts. The results show that the growth, measured through sales and employment, of SMEs in the service sector in Ecuador is not independent of firm size and therefore does not correspond to a random process.     

The Costs and Benefits of Regulation: Implications for Developing Countries

The literature on the benefits and costs of regulation demonstratesthat this issue can be explored systematically using standardeconomic analysis. It also shows that regulation can have asignificant adverse impact on economic growth. Specifically,regulation aimed at controlling prices and entry into marketsthat would otherwise be workably competitive is likely to reducegrowth and adversely affect the average standard of living.In addition, process regulation can impose a significant coston the economy. Nonetheless, social regulations may have significantnet benefits for the average consumer if designed judiciously. There are several policies developing countries might consideradopting to improve their general approach to regulation. Theappropriate regulatory tools and framework will depend on manyfactors, including bureaucratic expertise, resource availability,political constraints, and economic impacts. There is a generalneed to enhance the capability for evaluating regulation atthe local and national levels.      

Where does return and volatility come from? The case of Asian ETFs

We analyze return and volatility of Asian iShares traded in the U.S. The difference in trading schedules between the U.S. and Asia offers a unique market setting that allows us to distinguish various return and volatility sources. We find Asian ETFs have higher overnight volatility than daytime volatility, explained by public information released during each local market's trading session. Local Asian markets also play an important role in determining each Asian ETF return. Nonetheless, returns for these funds are highly correlated with U.S. markets, indicative of the effects of investor sentiment and location of trade. Finally, returns in the U.S. market Granger-cause returns in all six Asian markets are analyzed.     

Are women expected to be more generous?

This paper analyzes if men and women are expected to behave differently regarding altruism. Since the dictator game provides the most suitable design for studying altruism and generosity in the lab setting, we use a modified version to study the beliefs involved in the game. Our results are substantial: men and women are expected to behave differently. Moreover, while women believe that women are more generous, men consider that women are as generous as men.

Performance persistence and its influence on money and investor flows into Spanish pension plans

This article analyzes the phenomenon of performance persistence in Spanish equity pension plans between 1999 and 2006 to determine whether plans with higher performance in one period continue obtaining higher performance in the future. It also aims to determine the influence of past performance on investor behavior in order to examine whether money and investor flows of these portfolios are affected by past performance. The results reveal the existence of short-term performance persistence and a statistically significant relationship between historical returns and investment flows.

Monte Carlo valuation of natural gas investments

In this evaluation of energy assets related to natural gas, our particular focus is on a base load natural gas combined cycle power plant and a liquefied natural gas facility in a realistic setting. We also value several American-type investment options following the least squares Monte Carlo approach. We calibrate mean-reverting stochastic processes for gas and electricity prices by using data from NYMEX NG futures contracts and the Spanish wholesale electricity market, respectively. Additional sources of uncertainty concern the initial investment outlay, or the option's time to maturity, or the cost of CO₂ emission permits.     

The profitability of carry trades

The uncovered interest parity (UIP) condition suggests that carry trades whereby investors borrow in the low interest rate currency and invest in the high interest rate currency should not result in excess profits over the long run. In this paper, we test the significance of the conventional empirical failure of UIP condition. Using the four bilateral pound parities we fail to detect significant excess carry trade profits for the yen, euro and swiss franc–pound parities. The only parity for which the carry trade consistently makes excess profits is the dollar–pound parity. This result is somewhat surprising as this is the currency pair with the lowest interest rate differential. We are extremely grateful for the anonymous referee’s comments on this paper.     

The impact of unemployment on inequality and poverty in OECD countries

The purpose of this research is to examine the contribution of unemployment to income inequality and poverty in various OECD countries. These relationships have been explored using Luxembourg Income Study micro-data. Considerable differences across OECD countries are revealed through the use of within-household unemployment distributions. These differences help to explain most of the observed divergences in the relationship between unemployment and income distribution, in conjunction with the heterogeneous influence of social benefits on the economic position of the unemployed in these countries. A sub-group decomposition analysis corroborates the limited effect of unemployment on income distribution in most of the considered countries. However, it seems clear that the unemployed are among those with the highest risk of experiencing poverty.

A fractionally integrated model with a mean shift for the US and the UK real oil prices

In this article, we have modeled the log of the US and the UK real oil prices in terms of fractionally integrated processes with a mean shift. We used different versions of the tests of Robinson (1994), which have standard null and local limit distributions. The results indicated that if we model the series without a mean shift, then they are both non-stationary I(1). However, by including a mean shift component during the oil crises, they become fractionally integrated with an order of integration smaller than one and, thus, showing mean reverting behavior.     

Seasonal protection of F&V imports in the EU: impacts of the entry price system

The measures of border protection applied by the European Union (EU) to imports of fruits and vegetables (FV) are complex and usually not well represented in trade models, not only because of the range of instruments still constraining trade, but also because of product differentiation and seasonality in these products. This article assesses the impact of eliminating entry price (EP) constraints applied to a group of FV products. The proposed model is of a partial equilibrium nature and takes seasonality into account. We have applied the model to imports of tomatoes, cucumbers, clementines, and table grapes. Trade impacts of eliminating EP are significant for particular origins, during specific seasons, most notably for Moroccan tomatoes. The volumes and prices of products originating in the EU experience moderate reductions.
