Investment Incentives in Procurement Auctions 总被引:5,自引:0,他引:5
This paper investigates firms' incentives to invest in cost reduction in the first price sealed bid auction, a format largely used for procurement. Two central features of the model are that we allow firms to be heterogeneous and that investment is observable. We find that firms will tend to underinvest in cost reduction because they anticipate fiercer head-on competition. Using the second price auction as a benchmark, we also find that the first price auction will elicit less investment from market participants and that this is socially inefficient. These results have implications for market design when investment is important. 相似文献

How has wellbeing evolved over time and across regions? How does the West compare to the Rest? What explains their differences? These questions are addressed using a historical index of human development. A sustained improvement in world wellbeing has taken place since 1870. The absolute gap between OECD and the Rest widened over time, but an incomplete catching up—largely explained by education—occurred between 1913 and 1970. As the health transition was achieved in the Rest, the contribution of life expectancy to human development improvement declined and the Rest fell behind in terms of longevity. Meanwhile, in the OECD, as longevity increased, healthy years expanded. A large variance in human development is noticeable in the Rest since 1970, with East Asia, Latin America, and North Africa catching up to the OECD, and Central and Eastern Europe and Sub‐Saharan Africa falling behind. 相似文献

We document that immigrants in the United States differ from natives in several aspects relevant for their financial decision making. Based on these differences, we designed novel financial education materials targeted at US immigrants and their children and evaluated their effectiveness using a randomized control trial. To the best of our knowledge, this is the first rigorous evaluation of financial education programs targeted at this population. Compared to a control group, the groups that received the one‐time educational intervention were more likely to correctly answer financial knowledge questions immediately after the intervention. The estimated effects of this one‐time intervention on knowledge were large, but most of them faded away after six months. Moreover, we find little effect of the treatments on intended financial behavior measures, both immediately and six months later. Our results point to the efficacy of this type of educational material in informing immigrants and their children about important financial information that they are unfamiliar with, including information related to their immigrant status. However, they also suggest that a priority for future research should be to test whether repeated opportunities for learning can increase financial knowledge retention and lead to behavior change. 相似文献

Abstract The pessimistic flavour of the Human Development Reports appears to be in contradiction with their own numbers as developing countries fare comparatively better in human development than in per capita GDP terms. This paper attempts to bridge this gap by providing a new, ‘improved’ human development index (IHDI), informed by welfare economics. The IHDI is presented here alongside the United Nations Development Programme's (UNDP) HDI for the world and its main regions since the late 19th century. Social dimensions in the IHDI are derived, following Kakwani (Journal of Development Economics 41 (1993), pp. 307–336), with a convex achievement function, whereas a geometric average is employed to combine its dimensions (longevity, knowledge and income). Thus, the IHDI does not conceal the gap between rich and poor countries and casts a much less optimistic view than the conventional UNDP index, while it fits with the UNDP concern for international differences. The paper's findings highlight main weaknesses in human development dimensions of present‐day developing countries. 相似文献

Some recent papers have studied data from TV game shows to examine the behaviour of individuals towards risk. It is generally agreed that data from these shows are useful in detecting individual risk aversion in the field, with both “real life” subjects and incentives. Field experiments also include some interesting reality features that could affect individuals’ behaviour and possibly lead to different findings. This paper aims at investigating lab versus field evidence in risk taking attitudes, especially controlling for framing effects. To assess whether the behaviour of subjects in the field is consistent with that of experimental subjects, we designed an experiment to mimic (with experimental rewards and subjects) the rules of a well-known Italian TV game show, Affari Tuoi, in two different settings: a traditional lab setting, where the game was played individually (109 subjects) (Treatment 1); and a framed lab, in which the experiment was replicated in the Italian public television (RAI) studio where the show was actually recorded, with a smaller sample of undergraduate students (33) and in the presence of an audience (Treatment 2). Our comparison between the two different settings aims at establishing whether the presence of an audience, or of a situation that reproduces the stress that contestants must experience in the TV studio, can affect experimental subjects’ choices. We did not find any significant evidence of framing effects: students behave in a similar way in the two lab settings, responding essentially to incentives. Comparing the risk attitudes shown by experimental subjects in the two lab treatments with those exhibited by the contestants in the field, we found that contestants in the TV show are generally more risk averse than students in the lab. 相似文献

Years into the single currency, EMU financial markets are not fully integrated. We argue that the phenomenon can be better understood by looking at financial markets’ behavior in the wake of Italy’s monetary unification (1862). Variables such as the spread of the telegraph, trade volumes, and the diffusion of the ‘single currency’ fail to explain why it took 25 years for prices across regional stock exchanges to converge. A single Italian financial market appeared only when the State prevailed upon local vested interests by enforcing nation-wide financial market legislation. 相似文献

We develop three competing models of government budgeting: (1) a rational model, in which government services are provided in accordance with consumer tastes, (2) a Friedman-type model, in which spending and borrowing decisions derive from the level of taxes, and (3) a Buchanan public-choice type model, in which the extent of deficit spending determines government spending plans. We use quarterly U.S. data over the period 1947 to 1987 to empirically test each of these models within a vector autoregressive framework, taking into account the potential role of other relevant macro variables. We first specify the testing framework utilizing data on the levels of government revenue, spending and deficit, and show that the resulting estimates are unrealistic. We then divide each of these variables into anticipated and unanticipated components. The results thus obtained reject the Buchanan-type models, but are unable to reject either a Friedman-type model or a “weak” form of the rational model. Our results suggest that future research should concentrate on developing appropriate tests capable of distinguishing between these two models of the government budgeting process. 相似文献

This research aims to understand the process of cars' disposal, its context, its influences and its impacts on the meanings for consumers and their identities, as well as the new behaviours of these consumers when living without their car(s). We conducted, analysed and interpreted 20 in‐depth interviews with consumers that had previously owned at least one car and had no financial reasons for disposing of their car(s), but had decided to do it, and started to live without them, adopting alternative methods of transportation. Our findings show that these consumers faced a complicated process regarding the disposal of their car(s) but, due to the changes in their circumstances, they re‐signified relevant concepts that were connected to the ownership of a car: Their perception of freedom, comfort, safety and status changed during and after the disposal of their car(s). We also noticed that there were implications in terms of changes in their attitudes and behaviour as both citizens and consumers. As a contribution to the literature, our findings indicate that the re‐signifying of concepts related to possession of the object as well as changes in attitudes and behaviours that consumers undergo in the postdisposal stage, must be included in the model proposed for evaluating consumer behaviour in product disposal. 相似文献
