This paper identifies the empirical stylized features of consumer price setting behavior in Portugal using two micro-datasets
underlying the consumer price index. The main conclusions are: one in every four prices change each month; there is a considerable
degree of heterogeneity in price setting practices; prices of goods change more often than prices of services; price reductions
are common, as they account to around 40% of total price changes; price changes are, in general, sizeable; finally, the price
setting patterns seem to depend on the level of inflation as well as on the type of outlet.

We show that when instruments are nearly exogenous, the two stage least squares t-statistic unpredictably over-rejects or under-rejects the null hypothesis that the endogenous regressor is insignificant and Anderson–Rubin test over-rejects the null. We prove that in the limit these tests are no longer nuisance parameter free. 相似文献

We consider a principal-agent problem where the principal wishes to be endorsed by a sequence of agents, but cannot truthfully reveal type. In the standard “herding” model, the agents learn from each other's decisions, which can lead to cascades on a given decision when later agents' private information is swamped. We augment the standard model to allow the principal to subject herself to a test designed to provide public information about her type. She must decide how tough a test to attempt from a continuum of test types, which involves trading off the higher probability of passing an easier test against the greater impact from passing a tougher test. We find that the principal will always choose to be tested, and will prefer a tough test to a neutral or easy one. 相似文献

We study how the predictability and the decisiveness of electoral outcomes affect financial volatility. We argue that traders’ optimal investment strategies depend on their ability to make accurate electoral forecasts and the prospective losses associated with placing a bet on the wrong candidate. Using a triple difference‐in‐difference approach and data from two‐round presidential elections in five Latin American countries between 1999 and 2018, we find that financial volatility is greatest in the days immediately following unpredictable, decisive, elections. Postelectoral volatility also occurs following predictable, indecisive elections. The effect of learning the identity of the winning candidate on financial volatility is null when the election is unpredictable and indecisive, as well as when the election is decisive, but the outcome is predictable. These findings offer insights into investors seeking to hedge price risk around elections. They also have important implications regarding the relationship between public opinion polls and postelectoral financial volatility. 相似文献

This study investigates the increase in the labour force participation rate of women. We estimate a binary age–period–cohort
model for a sample of Dutch women born between 1925 and 1986. The results indicate that the increasing level of education
and the diminishing negative effect of children have played an important role. Moreover, we find important unobserved cohort
effects for pre-1955 generations, which is in line with results of studies on social norms. It is shown that the growth in
female participation is likely to slow down in the near future, as such cohort effects are not relevant for younger generations. 相似文献

Abstract Under congestion pricing, Canadian airports would annually save between $72 and $105 million. Social costs per landing and takeoff decrease about $300 at Toronto and Vancouver and $50 at Calgary and Montreal. Slot constraints fail to eliminate this airport congestion. Congestion prices are lower on average than existing weight‐based prices. Current airport capacity accommodates at least five more years of traffic growth before congestion reaches current levels. Substantial welfare gains occur even if dominant airlines already internalize their self‐imposed delays. This article calculates equilibrium congestion pricing schedules, traffic rates, queuing delays, layover times, and connection times by time of day. 相似文献

Prior research has concluded that socio-economic development does not significantly affect terrorism. We take an alternative view. First, we note that a country's socio-economic circumstances affect terrorists' behavior through terrorism's opportunity costs. We argue that this reasoning also holds for the case of supreme value terrorism. Then, we run a series of negative binomial regressions for 110 countries between 1971 and 2007 to test the hypothesis that poor socio-economic development is conducive to terrorism. We find that socio-economic variables indeed matter to terrorism, contrary to other results. Our findings imply that countries can benefit from economic development and growth in terms of a reduction in terrorism. 相似文献

Public good contributions may be affected by the social demand to contribute that is implicit in them. Sensitivity to social pressure predicts behavior in paired dictator and money burning games; the evidence for effects on public good contribution is mixed. 相似文献

In this article we evaluate a US Forest Service plan to mitigate damages from an invasive insect on public, forested land. We develop a dynamic model of infestation and control to explicitly account for biological interactions, baseline conditions, and uncertainty, thus creating a more complete picture of policy impacts than a static cost benefit analysis could provide. We combine the results of the dynamic model with an empirical study of nonmarket forest benefits to create a bioeconomic model of ecosystem management. Estimating the empirical model in a Bayesian framework allows us to treat the economic coefficients of the dynamic model as random variables. We specify distributions for the biological parameters and examine the effects of both biological and economic uncertainty on the predictive distribution of net benefits. We find that the net benefits of the program are positive, and that uncertainty in the biological model contributes substantially more to the variance of our estimate than does uncertainty over the valuation of the resource. 相似文献

Bargaining one-dimensional social choices 总被引:1,自引:0,他引:1
We analyze bargaining over the one-dimension characteristic of a public good among n impatient players when decisions require q favorable votes, q?2. Stationary subgame perfect equilibrium strategies are characterized for all games with deterministic protocol. We provide a monotonicity condition (satisfied by all single-peak, strictly quasi-concave and concave utilities) that assures uniqueness for every q whenever player's utilities are symmetric around the peak. Without symmetry, the monotonicity condition assures uniqueness for qualified majorities, q>n/2, provided that agents are sufficiently patient and utilities satisfy an additional regularity condition. Asymptotic uniqueness is assured for qualified majorities by imposing only the monotonicity condition. 相似文献
