Did the introduction of a nodal market structure impact wholesale electricity prices in the Texas (ERCOT) market?

Regression analysis suggests that zonal averages of locational marginal prices under the nodal market are about 2 % lower than the balancing energy prices that would occur under the previous zonal market structure in ERCOT. The estimates for the nodal market price effects are found after controlling for such factors as natural gas prices, total system load levels, non-dispatchable generation levels, the treatment of local congestion costs, and the treatment of the revenues received by the market from the auctioning of transmission rights. Our finding is limited to periods which are not characterized by price spikes in the wholesale market.     

Response of industrial customers to hourly pricing in Ontario’s deregulated electricity market

This paper uses hourly data from Ontario (Canada) between 2005 and 2008 to estimate the effects of real time wholesale electricity prices on demand by industrial customers. Nonlinear SUR estimates from Generalized Leontief (GL) specifications reveal elasticities of substitution from 0.02 to 0.07, confirming that industrial customers (connected to the transmission grid) shift consumption across peak and off-peak periods in order to reap benefits of lower prices. Estimates from FGLS and IV models suggest that this reduction in demand by industrial customers results in lower wholesale prices, which benefits all consumers. The policy lesson is that market based schemes that encourage Real Time Pricing (RTP) pricing should result in positive spillovers to all consumers.     

An experimental study of the impact of competition for Other People’s Money: the portfolio manager market

In this paper we experimentally investigate the impact that competing for funds has on the risk-taking behavior of laboratory portfolio managers compensated through an option-like scheme according to which the manager receives (most of) the compensation only for returns in excess of pre-specified strike price. We find that such a competitive environment and contractual arrangement lead, both in theory and in the lab, to inefficient risk taking behavior on the part of portfolio managers. We then study various policy interventions, obtained by manipulating various aspects of the competitive environment and the contractual arrangement, e.g., the Transparency of the contracts offered, the Risk Sharing component in the contract linking portfolio managers to investors, etc. While all these interventions would induce portfolio managers, at equilibrium, to efficiently invest funds in safe assets, we find that, in the lab, Transparency is most effective in incentivising managers to do so. Finally, we document a behavioral “Other People’s Money” effect in the lab, where portfolio managers tend to invest the funds of their investors in a more risky manner than their Own Money, even when it is not in either the investors’ or the managers’ interest to do so.     

Does computer-based training impact maintenance costs and actions? An empirical analysis of the US Navy’s AN/SQQ-89(v) sonar system

The United States Navy decided in the early 2000s to replace traditional, instructor-led schoolhouse training with computer-based training (CBT). While employing CBT may produce gains in knowledge acquisition and lower costs for repetitive, low-skill work, there is a lack of empirical evidence whether these benefits exist for more highly skilled Navy operations. Anecdotal evidence suggests that CBT failed to sufficiently prepare new sailors for sophisticated systems’ maintenance and operation. To determine the validity of this evidence, we examine how CBT has affected the AN/SQQ-89(v) sonar. We empirically analyse whether the Navy’s introduction of CBT significantly altered fleet maintenance costs, actions and training requirements, by assembling a unique data set of ships, locations, personnel, maintenance costs and maintenance actions. Controlling for the Navy’s plan to man the system, the number of authorized billets and the number of personnel on board, we find that CBT adversely impacts costs, actions and maintenance hours for the sonar system.     

Does growing wealth influence hedge funds’ development? An empirical analysis

Alternative investments, such as hedge funds, have, in last years, become an integral part of the investment portfolios of the wealthy. The article’s goal is also to answer the following research question: Does the global wealth of the world have impact on the global value of the hedge funds’ assets? We also try to forecast the value of the hedge funds’ assets for the next years 2015–2017. The results from this study would also be valuable to investors and other stakeholders, such as the regulators and the creditors of the hedge funds.     

Does European regional competitiveness influence sports? An analysis of three sports

The main objective of this work was to test European regional determinants of sports competitiveness. We studied competitiveness in volleyball, basketball and handball. We developed a theoretical model based on the model proposed by Bernard and Busse (2004) to analyse the effect of regional institutions and sport environments that can interfere with sports competitiveness. To test our model, we constructed an enlarged database for all European NUTS2 since 1995, which we analysed using panel data techniques (censored Tobit models). Our results reveal that the regions that are able to maintain player performance do so by persistent effort and external influences. These factors contribute more to regional competitiveness than a region’s central location or political prominence.     

Does Shariah compliance make interest rate sensitivity of Islamic equities lower? An industry level analysis under different market states

This paper examines the sensitivity of the Dow Jones Islamic market index and its corresponding industry equity indices to changes in the level, slope and curvature of the U.S. term structure of interest rates over the period 1996–2015 using the quantile regression approach. The empirical results reveal that the Islamic stock market has a considerable negative exposure to interest rate risk, although a declining time pattern of interest rate sensitivity is observed. The unexpected changes in the level factor of the U.S. yield curve, closely linked to long-term interest rates, are identified as the most important interest rate factor in explaining the variability of Islamic equity returns. Furthermore, the interest rate exposure tends to be stronger during extreme bearish conditions in the stock market, possibly due to the greater pessimism and risk aversion under these market circumstances. It is also shown that Islamic equities are not different from their mainstream counterparts in terms of interest rate sensitivity, indicating that the Islamic stock market does not provide a cushion against interest rate risk.     

Import-push or export-pull? An industry-level analysis of the impact of trade on firm exit

Does the selection effect of trade work solely through competition from imports, or does the export market further contribute to firm selection? This paper provides a re-interpretation of the different mechanisms in terms of selection on profitability—rather than productivity—and derives novel predictions regarding the export market and the role of product differentiation. Empirical results for a sample of Danish manufacturing industries confirm the import-“push” hypothesis as well as the export-“pull” hypothesis, but also reveal differences across industries. The selection effect of trade is mainly driven by the “import-push” if product differentiation is high, whereas it is driven by the “export-pull” if goods are homogeneous.     

Does the impact of private education on growth differ at different levels of credit market development?

Using an overlapping generations model, we show that the impact of private financing of education on growth depends on credit market development, being positive when credit markets are adequately developed but negative if sufficiently low levels of credit market development occur alongside relatively high private financing intensities. Employing cross-country data, we find that reduced-form growth relationships are statistically significant and robust under various controls and samples. We also lay out conditions under which economies with missing credit markets are dynamically efficient and outperform, in terms of growth, economies with complete credit markets. The latter may explain large cross-country differences in savings and growth, while facilitating the evaluation of policies on financing education.     

Do price-earnings ratios explain investment decisions better than Tobin’s q? Evidence from German firm-level data

This article tests the additional information content of price-earnings ratios, with respect to Tobin’s q, in explaining firms’ investment behaviour. While Tobin’s q describes the expected future earnings related to those projected by the book value, the price-earnings ratio compares future growth of earnings based on the projection of current earnings. In other words, a high price-earnings ratio might indicate that investors are willing to rely on future earnings growth, even though current earnings are low. By using an unbalanced panel of about 500 listed firms from Germany over the period 1987–2007, we find that including the price-earnings ratio in the investment equation does not change the explanatory power of Tobin’s q. Most notably, the price-earnings ratio exerts a positive and significant impact on investment. These results are robust to the inclusion of a measure of the firm’s internal funds and of fixed effects and also to the use of different estimators.     

Should I stay or should I go? An econometric analysis of retirement decisions by couples

This article analyses retirement decisions from a household perspective, treating the retirement timing of spouses as potentially interdependent choices. To identify the determinants of retirement decisions by couples and the effects of spousal retirement, this research estimates bivariate probit models in a multi-country setting. The results show a significant joint retirement trend: both men and women are more likely to retire if their spouse already has retired. Strong asymmetric behaviours arise by gender though, with high crosscountry heterogeneity, reflecting institutional differences in both pension and public health systems.     

The impact of innovation on companies’ performance: an entropy-based analysis of the STAR market segment of the Italian Stock Exchange

This paper proposes the use of a class of concentration-based entropy measures as a new instrument to quantify business performances through an analysis of growth, profitability and productivity. Such measures are tested against a complex analysis of the link between innovation and performance for firms listed in the STAR market segment of the Italian Stock Exchange. In so doing, two targets are achieved: (1) the identification of parameters that are relevant for explaining the relationship between innovation and performance for the considered sample, with special focus on innovation type, innovation level and business size; (2) the elaboration of a new methodology – based on information theory – for the analysis of the impact of innovation on performance. The study shows that type of innovation and size play a key role in determining company performance.     

Does human capital constrain the impact of foreign direct investment and remittances on economic growth in Ghana?

This article empirically investigates whether human capital constrains the impact of Foreign Direct Investment (FDI) and remittances on economic growth in Ghana. An economic growth model for Ghana is specified and estimated using Fully Modified Ordinary Least Squares (FMOLS) estimator and employing annual data spanning the period 1965 to 2008. Empirical results indicate that FDI and remittances are key determinants of economic growth in Ghana. Results indicate that human capital enhances the impact of FDI and remittances on economic growth. Although both government expenditure and trade openness are growth-enhancing, government expenditure appears to crowd-out private investment. Empirical results also indicate that domestic inflationary pressures, unstable political environment and volatile global economy exert a negative impact on economic growth in Ghana.     

Are subjective evaluations biased by social factors or connections? An econometric analysis of soccer referee decisions

Many incentive contracts are based on subjective evaluations and contractual disputes depend on judges’ decisions. However, subjective evaluations raise risks of favouritism and distortions. Sport contests are a fruitful field for testing empirically theories of incentives. In this paper the behaviour of the referees in the Italian soccer (football) league (“Serie A”) is analyzed. Using data on injury (or extra) time subjectively assigned by the referee at the end of the match and controlling for factors which may influence it (players substitutions, yellow and red cards, penalty kicks, etc.), we show that referees are biased in favour of home team, in that injury time is significantly greater if home teams are losing. The refereeing bias increases greatly when there is no running track in the stadium and the crowd is close to the pitch. Following the 2006 “Serie A” scandal we test whether favouritism emerges towards teams suspected of connections with referees finding that these teams obtain favourable decisions. Social pressure by the crowd attending the match however appears to be the main cause of favouritism. I would like to thank Francesco Aiello, Martin Brimble, Maria De Paola, Filippo Domma, Nicola Meccheri, Antonio Nicita, Michela Ponzo and two anonymous referees for useful comments. The usual caveats apply.     

An economic analysis of the Cattlemen’s Beef Promotion and Research Board demand-enhancing programmes

The research reported here addressed two objectives. The first objective was to measure the overall impact of the Cattlemen’s Beef Board as well as eight-specific advertising, promotion and research activities on US beef demand. The second objective was to compute marginal benefit–cost ratios (BCRs) for the eight individual checkoff activities and for the overall programme. The results indicated that Cattlemen’s Beef Board’s Promotion activities increased total domestic beef demand by 15.7 billion pounds in total, or 2.1 billion pounds per year between 2006 and 2014. Collectively, the overall marginal BCR for all Cattlemen’s Beef Board activities was $11.20.     

An ex-post analysis of the CME Group’s solution to the 5-year gap issue

In early 2001, the US Department of the Treasury suspended the issuance of 30-year bonds, and then resumed issuing its long paper in early 2006. As a result, there was a 5-year gap in the baskets deliverable into US T-Bond futures contracts expiring before 2016. In 2013, the CME Group raised the issue that grades contending for cheapest-to-deliver status were becoming significantly isolated from the rest of the basket because of this maturity gap. The aim of this article is to provide an ex-post assessment of the approach chosen by the CME Group to address this so-called ‘5-year gap issue’ and to compare its efficiency with that of an alternative solution that was not considered at the time.     

Does belief in objective morality lead to coercion? An analysis of the arguments of Kelsen and Buchanan

Two leading scholars of the 20th century – Hans Kelsen and James Buchanan – both suggested that belief in an objective morality entails a disparaging attitude towards political and individual freedom. The main point was similar: Why let people decide for themselves, whether in politics or ordinary life, if what is objectively right is known? This paper presents their arguments and evaluates them, both by specifying three conditions that need to be met for the arguments to hold (the objective morality must be believed to be known, a belief in a known morality must entail a motivation to see it followed and the content of the known morality must not block coercion) and by relating them to recent experimental research (which nevertheless provides some empirical support).     

Decentralized planning in a market economy? On the nature of Coase’s research program

By drawing attention to the planning islands of firm organizations in a market economy, Coase makes us believe that besides the price mechanism, there is another means of coordination, namely deliberate coordination. With the firm as an exemplary case of deliberate coordination was introduced into landscape of economics, Coase initiated a new research program which is to inquire into how efficiency is (and could be) achieved via various kinds of institutional arrangements, from the price mechanism, to firms, to government regulations. This paper acknowledges the positive role Coase has played in drawing economists’ attention to the generally neglected field of organizational research. It criticizes, however, his research program for viewing the economy, or society, from the perspective of some concrete decision-making entity.
