Regulatory arbitrage and the FERC rate settlement process

We demonstrate that the Federal Energy Regulatory Commission’s (FERC) regulatory procedures for natural gas pipelines, specifically its rate-refund policy, induces regulatory arbitrage that leads to economic distortions. Specifically, we demonstrate that the rate refund policy causes pipelines effectively to “extort” ratepayers through the addition of economically inefficient capital investment, akin to “gold-plating” investments. We estimate the potential magnitude of this arbitrage impact on ratepayers to be between $400 and $700 million annually. Counterintuitively, however, we demonstrate that the presence of this arbitrage opportunity leads to underinvestment in pipeline capacity, thus negating one of the principal purposes of rate regulation. We further demonstrate that FERC could easily eliminate this regulatory arbitrage by setting the refund interest rate to the pipeline’s as-filed weighted average cost of capital.     

The Role of Customer Factors in Multiple Store Patronage: A Cost-Benefit Approach

This paper is concerned with the use of multiple stores by supermarket customers. It relates the number of stores patronized to a set of customer factors under a unifying theoretical framework emphasizing cost-benefit analysis. Respective hypotheses are tested in a large random sample. This study is a first attempt to empirically address the structure of multiple store patronage. It is demonstrated that multiple store patronage is affected by variables such as customer income, satisfaction, and expenditure that are suggestive of heterogeneous cost-benefit tradeoffs and opportunity costs of time. It is shown that customers are intrinsically different in the predisposition to being loyal. In this respect, store patronage is a continuum between single store loyalty and use of several different stores, on which customers vary depending on individual preferences. The empirical analysis also suggests that exclusive patronage of the favorite store arises from two observationally equivalent latent segments that differ in their inclination to remain loyal. The results yield valuable insights into the structure of store patronage and lead to important implications for retail managers. Several extensions are considered. A broad set of research questions surrounding store patronage can be considered from a cost-benefit viewpoint in the sense that consumer decisions in this area involve trading off economic resources against assortment, spatial and temporal benefits.     

Innovation, rule breaking and the ethics of entrepreneurship

This article examines a feature of the ethics of entrepreneurship that is infrequently directly discussed, viz., rule breaking. Entrepreneurs are widely said to engage in rule breaking. Many examples of this appear in popular and academic literature. But how may this be integrated into an account of the ethics of entrepreneurship? One response would be that when entrepreneurs break legal and moral rules then what they do is wrong and ought to be condemned. There is a great deal to be said for this rule model of entrepreneurial ethics. However, this view is also mistaken. Instead, this article defends a virtue-based account of the ethics of entrepreneurship in which certain instances of rule breaking, even if morally wrong, are nevertheless ethically acceptable and part of the creative destruction that entrepreneurs bring not only to the economy but also to morality.     

Interest differentials and extreme support for uncovered interest rate parity

This paper addresses two findings from the empirical literature testing uncovered interest parity (UIP): (i) more favorable results when interest differentials (IDs) are large and (ii) instability across samples. Simulations demonstrate that explanations of the results using large IDs based on the hypothesis of a “zone of speculative inactivity” are inconsistent with empirical evidence. Furthermore, it is shown that, if agents forecast IDs based on long-run values, coefficient estimates will be unstable if rates of decay in IDs vary significantly and, for ex post UIP to hold, IDs must decay in absolute value. This is consistent with OECD country data.     

Performance Contracting In Practice: Experience and lessons from the water sector in Ghana

This article provides some insights into how performance contracting works in practice in a developing country context, using the case of the Ghana Water and Sewerage Corporation (GWSC). Performance contracting has been a useful instrument for restructuring the state-owned enterprises (SOE) sector in Ghana, and the GWSC has made some moderate improvements since its introduction. However, the article highlights some of the institutional constraints and capacity issues that reformers will have to pay attention to, including overstretched capacity of the monitoring agency, a weak information management system and inconsistent compliance to contract by government. The findings also highlight the difficulty of separating politics from operational/management issues, especially in politically sensitive public services, yet performance contracting relies on such separation to be effective. Also it shows how informal behaviour undermines the formality of performance contracting.     

Globalization vs. localization: global food challenges and local solutions

The objective of this study was to examine the effect of global–local interactions on food production and consumption in Ghana, and identify possible local solutions. Primary data were collected using a combination of quantitative‐qualitative methods, which included focus group discussions and one‐on‐one interviews. Approximately 450 household heads were randomly selected and interviewed between August 2007 and August 2008 in Eastern, Central, Upper East and Northern Regions of Ghana. Findings revealed increasing consumption of foreign rice as opposed to decreasing consumption of local rice and other staples like millet, sorghum and yam because of global–local interactions. However, opportunities exist to re‐localize production‐consumption patterns through the use of ‘glocal foods’ like improved ‘koose and waakye’. Referencing the situation in Ghana, the study recommends improved production and processing practices backed with appropriate technologies that reflect changing consumption dynamics in order to take full advantage of opportunities created as a result of global–local interactions.     

MULTIVARIATE METHODS FOR MONITORING STRUCTURAL CHANGE

Detection of structural change is a critical empirical activity, but continuous ‘monitoring’ for changes in real time raises well‐known econometric issues that have been explored in a single series context. If multiple series co‐break then it is possible that simultaneous examination of a set of series helps identify changes with higher probability or more rapidly than when series are examined on a case‐by‐case basis. Some asymptotic theory is developed for maximum and average CUSUM detection tests. Monte Carlo experiments suggest that these both provide an improvement in detection relative to a univariate detector over a wide range of experimental parameters, given a sufficiently large number of co‐breaking series. This is robust to a cross‐sectional correlation in the errors (a factor structure) and heterogeneity in the break dates. We apply the test to a panel of UK price indices.
