This study measures cost inefficiency of Kansas public school districts and applied both mathematical programming and stochastic
frontier approach. The empirical study uses two-stage data envelopment analysis model and the cost inefficiency effects model
proposed by Battese and Coelli (Empirical Economics 24:325–332, 1995) and applied to a panel data. The results found mean inefficiencies from these two models are very close. The results indicate
that Kansas school districts, on average, exhibit cost inefficiency in their operations, however, there is a tendency for
inefficiencies to decline over time. The study does not find any strong evidence for lower efficiency due to lower expenditure
per-pupil. Instead, we found inconclusive evidences where lower efficiency for certain school districts could be assigned
to unfavorable environmental cost conditions.

Schmitt-Grohé and Uribe (NBER wp 10724, 2004b) analyzes the optimal, simple and implementable monetary policy rules in a medium-scale macromodel, as the one proposed by
Christiano et al. (J Polit Econ 113:1–45, 2005). In doing so, they use a sensible, but somewhat arbitrary constraint to account for the lower bound condition on the nominal
interest rate. In this work, we check the robustness of their main results to such a criteria. We find that the optimal policies
are actually absolutely robust to the easing of this criterion for all the different cases considered.

This paper extends the prey–predator model of Grossman and Kim (J Political Econ 103:1275–1288, 1995) to analyze the relation between the value of a contested rent and the emergence of conflict. We show that an increase in
the value of the rent makes a conflict equilibrium more likely. We also analyze the case where the valuation of the rent is
different for the two players. We find, for example, that a conflict equilibrium may occur even though the predator has an
important disadvantage in warfare. That is when his valuation of the rent is sufficiently high compared to that of the prey.

We analyze a local interaction model where agents play a bilateral prisoner’s dilemma game with their neighbors. Agents learn
about behavior through payoff-biased imitation of their interaction neighbors (and possibly some agents beyond this set).
We find that the Eshel et al. (Am Econ Rev 88:157–179, 1998) result that polymorphic states are stochastically stable in such a setting is not robust. In particular, whenever agents
use information also of some agents beyond their interaction neighbors, the unique stable outcome is one where everyone chooses
defection. Introducing a sufficiently strong conformist bias into the imitation process, we find that full cooperation always
emerges. Conformism is thus identified as a new mechanism that can stabilize cooperation.

We analyse forecasts of professional forecasters for Germany regarding the time span from 1970 to 2004. This novel panel data set renders it possible to assess the accuracy and efficiency of growth and inflation forecasts more efficiently than in previous studies. We argue that the forecasts are, on average, unbiased and weakly—but not strongly—efficient. Using model confidence sets suggested by Hansen et al. (2004), we find that, besides the effect of diverging forecasting dates, no other substantial differences in forecasting quality among forecasters exist. Nevertheless, on the basis of a direction-of-change analysis we argue that it is not always advisable to listen to the majority of forecasters.

This study examines the impact of a stamp tax rate increase on market behavior, using data from two stock exchanges in China. We find that when the tax rate increases from 0.3 to 0.5% (which implies that the transaction cost increases by about 1/3) trading volume decreases by 1/3. This implies an elasticity of turnover with respect to a stamp tax of −50% and an elasticity of turnover with respect to transaction cost of −100%. The markets’ volatility significantly increases after the increase in the tax rate. Furthermore, the change in the volatility structure indicates that the markets become less efficient in the sense that shocks are less quickly assimilated in the markets.

In this article, using the data of 2008, we try to describe the impact of scale and product differentiation in 282 European
banks. While evidence of the economies of scale is less clear, the results obtained using a translogarithmic function system
show that significant economies of scope do exist even for new banking products like derivatives.

In this paper, by using a combination of long-run and short-run restrictions, we identify a small structural VECM which includes inflation, unemployment and the federal funds rate and study the dynamic interactions at different frequencies among these variables. Our results show that: (a) in accordance with the traditional view of economic fluctuations, aggregate demand shocks and monetary policy shocks push inflation and unemployment in opposite directions in the short run; (b) the permanent supply shock explains the long-run movement of inflation and unemployment. These conclusions are at odds with the prediction of “natural-rate” models but are consistent with the idea of a propagation mechanism which links productivity shocks to inflation and unemployment at medium and low frequencies. Thus, with respect to some recent studies (e.g. Beyer and Farmer, ECB Working Paper 121, 2002, and Ireland, J Monet Econ 44:279–291, 1999), we offer a different interpretation of the low-frequency comovements between inflation and unemployment characterizing the US economy in the last decades.

This short paper explores the relationship between investment and saving rates in a sample of 13 OECD countries over the period
1885–1992. To this end, I employ panel cointegration tests based on the maximum likelihood approach developed by Johansen
(J Economic Dynamics Control 12:231–254, 1988) instead of conventional panel cointegration residual based tests, in order to draw sharper conclusions. Using estimation
techniques appropriate for heterogeneous panels I find a low degree of capital mobility for the sub-periods 1921–1992 and
1950–1992. The findings overwhelmingly support the hypothesis of perfect capital mobility in the short run.

This paper centers on the structure of capital and the useful lives of its components by considering an economy with two representative
firms, one producing a necessity and another producing a luxury. This difference determines their reinvestment opportunities.
Therefore, while the one applies replacement, the other adopts scrapping. However, as these capital policies lead to different
service lives, the analysis confronts the issues raised by Miller (Review of Income and Wealth 29:284–296, 1982, Review of Income and Wealth 36:67–82, 1990) and deals with them by drawing on Haavelmo’s (A study in the theory of investment, Chicago: The University of Chicago Press, 1960) suggestions regarding the aggregation of capital. Among other findings, it turns out that the simulation results are highly
robust, thus demonstrating that real-world implications may be even stronger than strictly suggested by the model.

In this paper we analyze per capita incomes of the G7 countries using the common cycles test developed by Vahid and Engle
(Journal of Applied Econometrics, 8:341–360, 1993) and extended by Hecq et al. (Oxford Bulletin of Economics and Statistics, 62:511–532, 2000; Econometric Reviews, 21:273–307, 2002) and the common trend test developed by Johansen (Journal of Economic Dynamics and Control, 12:231–254, 1988). Our main contribution is that we impose the common cycle and common trend restrictions in decomposing the innovations into
permanent and transitory components. Our main finding is permanent shocks explain the bulk of the variations in incomes for
the G7 countries over short time horizons, and is in sharp contrast to the bulk of the recent literature. We attribute this
to the greater forecasting accuracy achieved, which we later confirm through performing a post sample forecasting exercise,
from the variance decomposition analysis.

The behavior of the exchange rate in the genetic algorithm with agents having long memory 总被引:1,自引:1,他引:0
Yiping Xu 《Journal of Evolutionary Economics》2006,16(3):279-297
This paper studies the behavior of the exchange rate in Kareken and Wallace (1981)'s model under the genetic algorithm adaptation with agents having long memory. The simulation results show that, if agents have full memory, the average portfolio fraction will converge, and the initial equilibrium that it converges to is history dependent. Under the lasting evolutionary pressure of the noise trader, the market will eventually drift from one equilibrium to another, and asymptotically will converge to the neighborhood of an equilibrium with agents putting their savings equally into two currencies. If the agents do not have full memory, the foreign exchange market will show periodic crisis. Before and after a market crises, the average portfolio fraction will converge to different stationary equilibria. A mean difference equation of the average portfolio fraction is also given to describe the dynamics of the model.

In this paper, we propose a new benchmarking procedure lying on cumulants for computing the factor loadings in financial models
of returns. We apply this technique to the well-known augmented Fama and French (J Fin Econ 43(2):153–193, 1997) model and compare it with another technique of ours based on higher moments. Our new procedure confirms the fact that the
alpha is supposed to decrease when we disaggregate HFR indices to the level of individual funds while correcting for specification
errors. Our new technique is therefore useful for hedge funds selection or ranking based on the alpha of Jensen corrected
for specification errors. This technique will also be useful for calibrating other financial models of returns like the simple
market model or the conditional alpha and beta models.

Firm survival: methods and evidence 总被引:1,自引:0,他引:1
This paper surveys the Industrial Organization literature on firm survival. We find that, in retrospect, the econometric specifications
used in this area have progressively become more sophisticated, addressing issues such as discrete time, unobserved heterogeneity
and competing risks. We also identify a number of firm- and industry-specific covariates that provide largely consistent results
across samples, countries and periods. On the other hand, the evidence is less clear-cut with regard to ownership and spatial
factors.

This paper provides empirical evidence on regional labor market flexibility in Europe and, in particular, in the EU-accession
countries in Central and Eastern Europe. Whereas substantial regional disparities in unemployment are found for pre-accession
EU member countries as well as for accession countries, an empirical analysis taking account of spatial effects shows that
regional wage flexibility is significantly higher for accession countries. Moreover, unemployment disparities are found to
be less persistent in the accession countries.

We explore the short-run dynamics and long-run relationship between income and financial development in Algeria, Egypt, and
Morocco. We use co-integration and VECM models and four indicators of financial development. The empirical results indicate
that there is a long-run relationship between income and each financial development indicator, except credit to the private
sector in Algeria. On the other hand, Granger-causality test results indicate that the evidence on the direction of causality
is mixed.

Economists inside and outside of the Austrian-school tradition have formulated a subjectivist theory of mineral resources.
While von Mises (1940) presented a rudimentary theory, institutionalist Zimmermann (1933 and after) provided an in-depth mind-centered approach
distinct from the objective, neoclassical theory for minerals developed by Jevons (1865, 1866), Gray (1913), and Hotelling (1931). A full-fledged Austrian theory identifies the fixity/depletionism view of minerals as incompatible with entrepreneurship.
Mineral resourceship, praxeologically akin to manufacturing, or the making of capital goods, demotes the distinction between depletable and nondepletable
resources for the sciences of human action. Instead of nonreproducibility, the interplay of geography and institutions becomes
the locus of mineral-resource theory, given the nonuniform distribution of deposits. An Austrian-institutional theory is more
robust for explaining changes in mineral-resource scarcity than neoclassical depletionism, and offers a wide research agenda
for current debates over resource production, usage, and future availability.

We use the Markov regime-switching ARCH (SWARCH) model of Hamilton and Susmel (J Econometrics 64:307–333, 1994) to document the presence of high volatility regimes in six Latin American countries (Argentina, Brazil, Chile, Mexico, Peru,
and Venezuela). We found four high volatility episodes, each associated to either a local (the Mexican crisis of 1994, the
Brazilian crisis of 1998–1999, the Argentinean crisis of 2001–2002) or a worldwide financial crisis (the Asian financial crisis
of 1997). However, we found that the effects of each financial crisis are short-lived and that between 2 and 4 months after
each crisis, all markets return to low volatility regimes.

The application of the rational choice postulate to a political context invariably leads to the conclusion that most voters
are ill informed when making the decision on whom to vote for. In this paper, the authors conduct an empirical evaluation
of the rational ignorance theory, based on the model developed by (Rogoff and Sibert Rev Econ Stud LV:1–16, (1988) and by considering that better informed voters reward political candidates who show better performances. The levels of performance
are established through the construction of an empirical frontier using the Data Envelopment Analysis (DEA) methodology. According
to our results, based on the 1997 Portuguese local elections, even though swing voters do not necessarily behave as rationally
ignorant voters, a large majority of voters are rationally ignorant.
