Is God in the details? A reexamination of the role of religion in economic growth

Barro and McCleary (2003, Religion and economic growth across countries. American Journal of Sociology 68 : 760–781) is a key research contribution in the new literature exploring the macroeconomic effects of religious beliefs. This paper represents an effort to evaluate the strength of their claims. We evaluate their results in terms of replicability and robustness. Overall, their analysis generally meets the standard of statistical replicability, though not perfectly. On the other hand, we do not find that their results are robust to changes in their baseline statistical specification. When model‐averaging methods are employed to integrate information across alternative statistical specifications, little evidence survives that religious variables help to predict cross‐country income differences.

The long-run relationship between stock prices and goods prices: New evidence from panel cointegration

We examine the long-run relationship between stock prices and goods prices to gauge whether stock market investment can hedge against inflation. Data from 16 OECD countries over the period 1970–2006 are used. We account for different inflation regimes with the use of sub-sample regressions, while maintaining the power of tests in small sample sizes by combining time-series data across our sample countries in a panel unit root and panel cointegration econometric framework. The evidence supports a positive long-run relationship between goods prices and stock prices with the estimated goods price coefficient being in line with the generalized Fisher hypothesis.     

Stock liquidity and investment opportunities: New evidence from FTSE 100 index deletions

This paper examines the relationship between stock liquidity and investment opportunities in a sample of firms experiencing a negative exogenous liquidity shock, captured by deletion from the FTSE 100 stock index. We find no statistical association between stock liquidity and investment opportunities. These findings are in sharp contrast to the positive relation between liquidity and investment opportunities reported in US equity markets. This unique result in the London Stock Exchange suggests that deletion from a major stock index does not influence corporate investment decisions because there is no significant change in the cost of capital.     

Non-linearity versus non-normality in real exchange rate dynamics

We distinguish non-normality from non-linearity in G7 real exchange rate dynamics by correcting the critical values of the Kapetanios et al. [Kapetanios, G., Shin, Y., Snell, A., 2003. Testing for a unit root in the non-linear STAR framework. Journal of Econometrics, 112, 359–379] test for non-normality using the wild bootstrap. Our findings validate non-linear Purchasing Power Parity net of non-normality effects.     

Do brokers act in the best interests of their clients? New evidence from electronic trading systems

Prior research suggests brokers do not always act in the best interests of clients, although morally obligated to do so. We empirically investigated this issue focusing on trades executed at best execution price, before and after the introduction of electronic limit‐order trading, on the London Stock Exchange. As a result of limit‐order trading, the proportion of trades executed at the best execution price for the customer significantly increased. We attribute this to a sustained increase in the liquidity of stocks as a result of limit‐order trading, regardless of market capitalisation. We discuss the ethical implications of our findings and conclude that market structures that enhance market competitiveness may help reconcile broker and client interests.     

Liquidity Constraints and Investment Opportunities: New Evidence from Large and Small Businesses in the UK

In this paper, we compare the liquidity constraints and investment opportunities for large and small businesses. This is done by examining the relationship between stock liquidity and investment opportunities in a sample of large and small enterprises listed on the London Stock Exchange. We find a positive statistical association between stock liquidity and investment opportunities, regardless of the size of the enterprise. This unique result in the London Stock Exchange suggests that firm size does not influence corporate investment decisions because there is no significant change in the cost of capital between large and small enterprises.     

INFLATION TARGETING AND THE STATIONARITY OF INFLATION: NEW RESULTS FROM AN ESTAR UNIT ROOT TEST

In this paper, we examine the time series properties of inflation in seven countries that have adopted inflation targeting. Unlike previous studies, we utilize a non‐linear mean reverting adjustment mechanism for inflation and we discover that, although deviations of inflation from the target can exhibit a region of non‐stationary behaviour, overall they are stationary indicating successful targeting implementation.     

Hedging under the influence of transaction costs: An empirical investigation on FTSE 100 index options

The Black–Scholes (BS; F. Black & M. Scholes, 1973) option pricing model, and modern parametric option pricing models in general, assume that a single unique price for the underlying instrument exists, and that it is the mid‐ (the average of the ask and the bid) price. In this article the authors consider the Financial Times and London Stock Exchange (FTSE) 100 Index Options for the time period 1992–1997. They estimate the ask and bid prices for the index, and show that, when substituted for the mid‐price in the BS formula, they provide superior option price predictors, for call and put options, respectively. This result is reinforced further when they .t a non‐parametric neural network model to market prices of liquid options. The empirical .ndings in this article suggest that the ask and bid prices of the underlying asset provide a superior fit to the mid/closing price because they include market maker's, compensation for providing liquidity in the market for constituent stocks of the FTSE 100 index. © 2007 Wiley Periodicals, Inc.

Risk aversion,exchange‐rate uncertainty,and the law of one price: insights from the market for online air‐travel tickets

Abstract We argue that risk aversion driven by exchange‐rate uncertainty causes a wedge between the domestic and foreign prices of a homogeneous good. We test our hypothesis using a unique micro‐data set from a market with minimum imperfections. The empirical findings validate our hypothesis, as accounting for exchange‐rate uncertainty we are able to explain a significant proportion of deviations from the law of one price. Overall, our analysis suggests the possibility of a new solution to the purchasing power parity puzzles.
