We test the efficiency of the California electricity reserves market by examining systematic differences between its day- and hour-ahead prices. We uncover significant day-ahead premia, which we attribute to market design characteristics. On the demand side, the market design established a principal–agent relationship between the markets' buyers (principal) and their supervisory authority (agent). The agent had very limited incentives to shift reserve purchases to the lower priced hour-ahead markets. On the supply side, the market design raised substantial entry barriers by precluding purely speculative trading and by introducing a complicated code of conduct that induced uncertainty about which actions were subject to regulatory scrutiny. We use a high-dimensional vector moving average model to estimate the premia and conduct correct inferences. To obtain exact maximum likelihood estimates of the model, we develop a new EM algorithm that seamlessly incorporates missing data and applies directly to general moving average time series models. Our algorithm uses only analytical expressions: the Kalman filter and a fixed interval smoother in the E step and least squares-type regressions in the M step.

We propose the grouped coefficients estimator to reduce bias in dynamic panels with small T that have a multilevel structure to the coefficient and factor loading heterogeneity. If groups are chosen such that the within-group heterogeneity is small, then the grouped coefficients estimator can lead to substantial bias reduction compared to pooled GMM dynamic panel estimators. We also propose using a Wald test that can be used to assess whether pooled estimators suffer from heterogeneity bias. We illustrate the usefulness of grouped coefficients with an application to labour demand in which the coefficients are grouped by sub-sector. Our results suggest that the standard pooled estimates are substantially biased.  相似文献

This paper examines the compliance behaviour of a dominant firm in an output quota market when the firm is able to exercise market power in both the quota and the output markets. Provided the firm has an initial quota endowment which is strictly positive, under some circumstances the firm may find it profitable to comply or even over-comply in its quota demand, even in the absence of enforcement. The results are compared to those found in the pollution permit literature for a firm with market dominance only in the permit market, to which some additional observations are also added concerning efficiency outcomes under non-compliance.  相似文献

Competition policy attempts to address the potential for market failure by encouraging competition in service markets. Often, in wireless communication service markets, national regulatory authorities seek to encourage entry via the spectrum assignment process. Instruments used include the assignment mode (auction or beauty contest), setting aside licenses and providing bidding (price and quantity) credits for potential entrants, and making more licenses (spectrum blocks) available than there are incumbent firms (excess licenses). The empirical analysis assesses the effectiveness of these policy instruments on encouraging entry. The econometric results show that the probability of entry is enhanced by using auction assignments and excess licenses. Furthermore, quantity, but not price, concessions encourage entry.  相似文献

We develop a model of simple “reputation systems” that monitor and publish information about the behavior of sellers in a search market with asymmetric information. The reputations created influence the equilibrium search patterns of buyers and thus provide for market‐based “punishment” of bad behavior. We show that a reputation system that rewards honesty can enhance welfare by allowing good sellers to truthfully signal their type. However, the same system can be prone to strategic manipulation by sellers who always have low‐quality products. In that case, we show that an alternative system which assigns reputations based on product quality rather than honesty can be superior.  相似文献

This paper examines whether price level or inflation targeting would have been appropriate policy choices for Japan during its disinflation and deflation period. We employ Markov switching and structural vector autoregressions, together with structural IS equations, to investigate monetary policy effectiveness during the Japanese disinflation. We find evidence of regime switching in the mid-1990s in a model including the nominal policy interest rate. When monetary policy shocks are identified by using the McCallum rule for monetary base, a monetary expansion is found to have a statistically significant impact on prices. Moreover, a lower real ex ante interest rate can still stimulate the economy despite the zero lower bound on nominal interest rates.  相似文献

This paper adds to the literature on wealth effects on consumption by disentangling house price effects on consumption for mainland China. In a stochastic modelling framework, the riskiness, rate of increase and persistence of house price movements have different implications for the consumption/housing ratio. We exploit the geographical variation in property prices by using a quarterly city‐level panel data set for the period 1998Q1–2009Q4 and rely on a panel error correction model. Overall, the results suggest a significant long‐run impact of property prices on consumption. They also broadly confirm the predictions from the theoretical model.  相似文献

This study builds on insights from both upper echelons and agency perspectives to examine the effects on corporate social responsibility (CSR) practices of CEO's narcissism. Drawing on prior theory about CEO narcissism, we argue that CSR can be a response to leaders' personal needs for attention and image reinforcement and hypothesize that CEO narcissism has positive effects on levels and profile of organizational CSR; additionally, CEO narcissism will reduce the effect of CSR on performance. We find support for our ideas with a sample of Fortune 500 CEOs, operationalizing CEO narcissism with a novel media‐based measurement technique that uses third‐party ratings of CEO characteristics with validated psychometric scales.

Research summary: Building on research in strategic management that has found that high levels of pay dispersion are detrimental to firm performance; we examine the potential dependence of those findings on similar dispersion in the latent potential of those resources to contribute to performance. We find that congruence between resource value dispersion and pay dispersion is positively related to organizational performance. Additionally, we find that this congruence moderates the effects of both organizational resources and organizational pay levels on organizational performance. These findings contribute to a growing line of research that explores the implications of key human resource value and pay combinations for organizational performance. Managerial summary: While differences in income between key employees (i.e., dispersed pay) can instill feelings of inequity and be detrimental to organizational performance, such differences may also increase the odds of attracting star talent and help performance. In the context of Major League Baseball (MLB), we find that performance improves when dispersions in pay are congruent with the dispersion in the contributions that team members make to their organizations. We also find that the positive effects on performance of higher total pay and of level of organizational talent are enhanced by congruent pay and contribution dispersions. These findings suggest organizations may benefit from consistent dispersions in pay and talent and that important contributions by key organizational members need to be visible when organizations have dispersed pay structures.

Robert Angevine’s excellent monograph offers valuableinsights for historians of technology, business, and the military.This book details the "symbiotic" relationship of railroadsand the military, showing how the relationship evolved duringthe nineteenth century. Angevine lays out his story chronologically. The fact that theUnited States was going to need some sort of transportationinfrastructure in order to move troops in a timely manner wasfirst realized after the War of 1812. As a result,  相似文献
