Spot and forward markets for natural gas: The effects of state regulation

Since the emergence of a spot market in natural gas in 1984, state regulators have been concerned that regulated utilities would fail to choose between contracts and spot purchases in a way that minimizes costs. Grounds for this concern are shown, under two alternative rate structures, in a model where regulation produces ex post profit and loss restrictions. Two policy resolutions to the problem are suggested, one that uses an alternative mechanism for triggering rate reviews, allowing the substitution of ex ante for ex post profit and loss restrictions, and one that exploits the special structure of gas markets within the context of traditional regulatory practice.     

Founders versus non-founders in large companies: financial incentives and the call for regulation

This paper is intended to question some of the premises in the ever increasing calls to regulate executive pay. We focus on founders, and extend Shleifer and Vishny’s (1989, Journal of Political Economy, 94, 461–488) manager-specific investments model by explicitly modeling managerial effort and pay performance sensitivity. Tests of this model on a data set of large companies, controlling for the endogeneity of managerial compensation, indicate that founders tend to be less responsive to performance incentives and generally more entrenched. At the same time, founders’ led firms are more valuable, supporting our predictions. This suggests that for founders, regulation of compensation may not be very effective.      

Testing for efficiency in selected developing foreign exchange markets: An equilibrium-based approach

This paper proposes an alternative way of testing FOREX efficiency for developing countries. The FOREX market will be efficient if fully reflects all available information. If this holds, the actual exchange rate will not deviate significantly from its equilibrium rate. Moreover, the spot rate should deviate from its equilibrium rate by only transitory components (i.e. it should follow a white noise process). This test is applied to three Central and Eastern European Countries — members of the EU. Considering an LSTAR model we find no evidence of nonlinear adjustment in the misalignment series. So, linear unit root tests imply that the Poland/Euro FOREX market is efficient, the Czech/Euro FOREX market is not, while the Slovak/Euro FOREX market is quasi-efficient.     

Modelling non-performing loans probability in the commercial banking system: efficiency and effectiveness related to credit risk in Italy

In this article, we model the effect of the non-performing loans on the cost structure of the commercial banking system. With this aim, we comment on an increase in the non-performing loans by studying the consequences of such a change on the cost function and compute the probability of failure of maintaining a performing loan as such. In doing so, we are convinced that geography does matter and evaluate the risk propensity of the bank towards the non-performing loans accordingly. We finally stress that traditional efficiency indicators of cost elasticity do not fit properly with such a problem and propose a measure based on the costs for managing and monitoring the loans which, according to the related density function, will reveal effectively as non performing.     

The incentives for supply chain collaboration to improve material efficiency in the use of steel: An analysis using input output techniques

In the face of increasing demand and limited emission reduction opportunities, the steel industry will have to look beyond its process emissions to bear its share of emission reduction targets. One option is to improve material efficiency — reducing the amount of metal required to meet services. In this context, the purpose of this paper is to explore why opportunities to improve material efficiency through upstream measures such as yield improvement and lightweighting might remain underexploited by industry. Established input–output techniques are applied to the GTAP 7 multi-regional input–output model to quantify the incentives for companies in key steel-using sectors (such as property developers and automotive companies) to seek opportunities to improve material efficiency in their upstream supply chains under different short-run carbon price scenarios. Because of the underlying assumptions, the incentives are interpreted as overestimates. The principal result of the paper is that these generous estimates of the incentives for material efficiency caused by a carbon price are offset by the disincentives to material efficiency caused by labour taxes. Reliance on a carbon price alone to deliver material efficiency would therefore be misguided and additional policy interventions to support material efficiency should be considered.     

Testing for weak-form efficiency of crude palm oil spot and future markets: new evidence from a GARCH unit root test with multiple structural breaks

There is a sizeable literature that tests for weak-form efficiency in commodity and energy spot and future prices. While many studies now allow for multiple structural breaks to address the criticism that conventional unit root tests have low power to reject the unit root null in the presence of structural change, the extant literature overlooks the fact that conventional unit root tests are biased in the presence of conditional heteroscedasticity. We apply a recently developed generalized autoregressive conditional heteroscedasticity (GARCH) unit root test with multiple structural breaks to crude palm oil spot and future prices and find much more evidence against weak-form efficiency than that found using tests that fail to allow for conditional heteroscedasticity. Our results point to the importance of allowing for heteroscedasticity when testing for efficiency in commodity and energy spot and future prices.

A Modest Proposal for a Two‐Sided Market Clearing Institution under Asymmetric Supply Constraints with Skewed Pricing: The Market for Adoption and Abortion in the United States

This paper presents a theoretical model matching the potential supply of terminated pregnancies with the total demand for children within certain modeling constraints. First, the demand and supply of pregnancies should be studied within the theoretical framework of a market with economic incentives. Second, a theoretical model for the demand for abortion must incorporate the total market for children, which implies the market for pregnancy, abortion, and adoption. Third, there exist in the overall market for procreative goods and services certain unique characteristics that need to be carefully considered. Producers and suppliers within the procreative goods and services market have radically different price and cost elasticity functions and unique production asymmetries that create a potential net benefit for buyer and seller alike. The market for abortion and adoption, while seemingly related and similar, suffer from a fundamental disconnect, preventing a simple exchange of goods and services: abortion implies potential supply that does not flow to potential consumersthose seeking to adopt. Studying this market inefficiency will benefit from a two‐sided market analysis used in situations where an intermediary business must attract both producers and suppliers. There are two key findings. First, I find that the producer decision to supply the good depends primarily on exogenous preference formation and not on consumer‐provided incentives. Second, I find that the market would benefit from legal framework for a market clearing institution using the market for real estate as the blueprint.
