Summary. Starr (1973) showed that, if people have different subjective probabilities, ex ante and ex post efficiency conflict. Conversely, under the simple preferences that he considered, the discrepancy between ex ante and ex post efficiency disappears when subjective probabilities are identical. Here I consider identical subjective probabilities, but
more general preferences. First, risk attraction is admitted. Second, I dispense with the double requirement (dubbed IZU)
of additive separability and state-independence of the utility of zero-date consumption, an unrealistic requirement when modeling
the investment in durable goods. I find that, under IZU, and as long as ex post preferences satisfy the natural assumption of quasiconcavity (and satisfy some technical qualifications), an ex ante efficient allocation is indeed ex post efficient, but the converse is not necessarily true under risk attraction. If, on the other hand, IZU is violated, then one
can have ex ante efficient allocations that are not ex post efficient, and vice-versa, even under risk aversion.

Summary. This paper presents a general procedure for finding profiles with the minimum number of voters required for many important
paradoxes. Borda's and Condorcet's classic examples are revisited as well as generalizations. Using Saari's procedure line,
we obtain an upper bound for the minimum number of voters needed for a profile for which the Condorcet winner is not strictly
top ranked for all weighted positional procedures. Also we give a simple upper bound on the minimum number of voters needed for a set of prescribed voting outcomes. In contrast to situations wherein small numbers of voters are needed, we consider paradoxes
requiring arbitrarily large numbers of voters as well as large numbers of alternatives. Finally we indicate connections with
statistical rank based tests.

The lexicographic composition of reflexive and complete binary relations (which are often called abstract games) is studied.
The necessary and sufficient conditions are obtained for a lexicographic composition of quasi transitive relations to be quasi
transitive.The case of acyclicity of lexicographic composition of two relations is also investigated.

We consider whether oil prices can account for business cycle asymmetries. We test for asymmetries based on the Markov switching
autoregressive model popularized by Hamilton (1989), using the tests devised by Clements and Krolzig (2000). We find evidence
against the conventional wisdom that recessions are more violent than expansions: while some part of the downturn in economic
activity that characterises recessionary periods can be attributed to dramatic changes in the price of oil, post-War US economic
growth is characterized by the steepness of expansions.

We compare a number of models of post War US output growth in terms of the degree and pattern of non-linearity they impart
to the conditional mean, where we condition on either the previous period's growth rate, or the previous two periods' growth
rates. The conditional means are estimated non-parametrically using a nearest-neighbour technique on data simulated from the
models. In this way, we condense the complex, dynamic, responses that may be present in to graphical displays of the implied
conditional mean.

This paper employs duration analysis to investigate the timing of default in the UK mortgage market. Our analysis is performed on an ex ante basis, in that our explanatory variables are available to mortgage lenders when the loan is first made. We estimate both standard Weibull distributions and generalizations of the Weibull that permit non-monotonic hazard functions. The models fit the data well, suggesting that we have captured the major sources of variation in duration. We find that ‘cash flow’ variables, such as salary and interest rate paid, play the largest role. Surprisingly, loan-to-value ratios are either insignificant or influence default times in a counter-intuitive direction. 相似文献

The New York State Environmental Externalities Cost Study and computerized externality model (EXMOD) are used to examine the specification of methods design and application factors in the computation of electricity externalities. We report the sensitivity of externality estimates with alternative specifications for 15 different factors in the analysis, including the selection of facility type, site, and operating characteristics; air emission assumptions and air modeling procedures; dose-response assumptions; economic valuation assumptions; and other modeling procedures and assumptions. Many of the factors that most influence externality computations can be well specified in the analysis, such as the facility type, age, characteristics, emission rates, whether there is SO2 trading, and the inclusion of long range impacts. Most significant among the factors for which there remains significant scientific uncertainty are the selection and application of air dispersion models, selection of air pollution thresholds for health impacts, reduced life span risks associated with ozone exposure and with long-term exposure to PM10, values for CO2 damages, and the value to be applied to increased risks of reduced life span for individuals age 65 or older. 相似文献

Summary. For Bertrand duopoly with linear costs, we establish via a single (counter-)example that: (i) A new monotone transformation
of the firms' profit functions may lead to the supermodularity of transformed profits when the standard log and identity transformations
both fail to do so, and (ii) Topkis's notion of critical sufficient condition for monotonicity of a Bertrand firm's best-reply
correspondence cannot be extended to rely only on positive unit costs.

Summary. We prove existence of a competitive equilibrium in a version of a Ramsey (one sector) model in which agents are heterogeneous
and gross investment is constrained to be non negative. We do so by converting the infinite-dimensional fixed point problem
stated in terms of prices and commodities into a finite-dimensional Negishi problem involving individual weights in a social
value function. This method allows us to obtain detailed results concerning the properties of competitive equilibria. Because
of the simplicity of the techniques utilized our approach is amenable to be adapted by practitioners in analogous problems
often studied in macroeconomics.
