The development of retail brands has been favoured by the creation of large chains and by the high level of business concentration in the retail sector. It has been supported by an increasing number of consumers who are aware of value and consider that retail brand is the best alternative, with quality levels similar to those of leading manufacturer brands but with lower prices. In this survey, we analyse the price differentials between manufacturer brands and retail brands in several categories of widely consumed products. We study the relationship between the price differential and the mean category price with the market share of retail brands, for foodstuff, perfumes and cleaning materials categories. Finally, we determine the possible connection between the price of a consumer good brand and its real quality.  相似文献

Several regulatory authorities worldwide have imposed forward contract commitments on electricity producers as a way to mitigate their market power. In this paper we analyze the impact of such commitments on equilibrium outcomes in a model that reflects important institutional and structural features of electricity markets. We show that, when firms are asymmetric, the distribution of contracts among firms matters. In the case of a single dominant firm, the regulator can be confident that allocating contracts to that firm will be pro-competitive. However, when asymmetries are less extreme, certain contract allocations might yield anti-competitive outcomes by eliminating more competitive equilibria. Our analysis thus suggests that forward contracts should be allocated so as to (virtually) reduce asymmetries across firms.  相似文献

We document information rigidity in forecasts of real GDP growth in 46 countries over the past two decades. We also investigate: (i) whether rigidities differ across countries, particularly between advanced countries and emerging markets; (ii) whether rigidities are lower around turning points in the economy, such as in times of recessions and crises; and (iii) how quickly forecasters incorporate news about growth in other countries into their growth forecasts, with a focus on the way in which advanced countries’ growth forecasts incorporate news about emerging market growth, and vice versa.  相似文献

This paper explores the effect of the possibility of third-party intervention on behavior in a variant of the Berg et al. [Berg, J., Dickhaut, J., McCabe, K., 1995. Trust, reciprocity and social history. Games and Economic Behavior 10, 122–142] “Investment Game”. A third-party's material payoff is not affected by the decisions made by the other participants, but this person may choose to punish a responder who has been overly selfish. The concern over this possibility may serve to discipline potentially selfish responders. We also explore a treatment in which the third party may also choose to reward a sender who has received a low net payoff as a result of the responder's action. We find a strong and significant effect of third-party punishment in both punishment regimes, as the amount sent by the first mover is more than 60% higher when there is the possibility of third-party punishment. We also find that responders return a higher proportion of the amount sent to them when there is the possibility of punishment, with this proportion slightly higher when reward is not feasible. Finally, third parties punish less when reward is feasible, but nevertheless spend more on the combination of reward and punishment when these are both permitted than on punishment when this is the only choice for redressing material outcomes.  相似文献

This paper studies contribution of capital deepening, technological progress and efficiency improvement to economic growth while focusing on cross-country data, and thus finds itself at the crossroads of growth and development accounting. We take a production frontier approach to growth accounting and choose DEA as the frontier estimation method. To explore the effects that windfall gains from natural resource use have on growth, output data are corrected for pure natural resource rents—part of GDP figures not earned by either labor or capital. Taking into account countries’ natural resources, we find that in the two decades from 1970 to 1990 the average contribution of technological catch-up to per worker output growth was, if anything, negative on the worldwide scale and this trend continued till the mid 1990ies. Analysis of efficiency estimates also shows a possible change over the period of 1970–1990 in the effect of natural resources on country’s performance  相似文献

This article constructs a game‐theoretic model in which high chief executive officer (CEO) pay emerges as the outcome of an arms race, with each firm hiring a highly paid CEO to protect its competitive position against rivals who also hire highly paid CEOs. For an arms race to emerge, highly paid CEOs must generate idiosyncratic, privately known internal effects on profit, and CEO pay disparities must also generate asymmetric profit differences from external effects beyond the simple differences in pay. If the distribution of internal effects satisfies a key uniformity condition, an arms race emerges as the only equilibrium of the game.  相似文献

This study examines the impact of SFAS 141 on earnings predictability of merging firms. I expect a relative improvement in analysts’ earnings forecast accuracy for merging firms versus non-merging peers after SFAS 141 adoption. I restrict the post-SFAS 141 sample to the initial year of SFAS 141 implementation. This research design disentangles effects of SFAS No. 141 from those of SFAS No. 142. The evidence from analysis of 48 pairs of merging and matched non-merging firms is consistent with expectations and confirms the increase in earnings predictability for merging firms versus their non-merging peers post-SFAS 141. Results of additional tests suggest that earnings predictability improvement more likely follows from extended disclosure requirements and the other changes in the Purchase Method (“better purchase” issue) than from the elimination of Poolings-of-Interest (“purchase vs. pooling” issue).  相似文献

Farmers in low‐income rural economies often fail to switch to cash crops from staple production despite the positive income effects of commercialization expected by policy makers. The literature suggests that market failures prevent households from cash crop adoption but remains inconclusive regarding farmers' motives and the effects of commercialization. This article contributes to the debate by offering an original approach to the analysis of commercialization outcomes and farmers' decisions. It consists of applying a model with essential heterogeneity and a semiparametric estimation technique to analyzing harvest value returns to cash cropping. Using Malawian data, we show considerable heterogeneity in harvest value returns to cash cropping both within and between groups of farmers choosing different crop portfolios. Importantly, the results imply rational choices based on comparative advantage considerations of farming households: farmers self‐select into the activity where they expect higher gains and adopt cash crops when facing weaker market barriers.  相似文献

In this paper we develop a theoretical model with a representative bank whose ownership is shared between state and private sector. The bank faces a risk of failure and provides private and public explicit deposit insurance. Banks owned to a larger extent by the government are more able to counteract a restrictive monetary policy because of their capacity to raise additional volume of deposits. Therefore, the greater the state’s share in the bank ownership, the less the impact of a monetary tightening on the level of loan supply.  相似文献

It is widely acknowledged that landscape features can play a major role in determining tourism demand. The present article assesses the impact of vinery landscape and high‐quality wine production on regional tourism flows in Tuscany, an important tourist region in Italy and renowned for its enchanting countryside. Thus, vinery landscape and high‐quality wine production have been included as explanatory variables in our model for tourism flows. This model has been estimated for both international and domestic markets for the whole region of Tuscany. Estimation results confirm that land areas devoted to the production of these superb Tuscan wines, in the particular case of Siena including the Brunello di Montalcino, play an important role in explaining international tourism flows. In this context, we estimate climate‐change‐induced impacts on vinery landscape and quality wines in the tourism sector. These are estimated to cause a loss in the tourism revenues of nearly 15 and 20 million Euros a year, respectively, for 2020 and 2050, for the Tuscany region. Such losses are quite significant, and reiterate the urgency to identify and implement adequate policy options so as to moderate such land use changes, and respective negative welfare impacts.  相似文献
