This paper corrects and extends the analysis in Social Identity, Inequality, and Conflict by James Robinson (Economics of Governance, 2(1), 2001). For conflict along class lines, Robinson finds the total impact of mobility on conflict to be ambiguous. Contrary to his result, I show that, under his assumptions, the effect of social mobility on class conflict is unambiguous. Higher mobility always decreases conflict. In my extension to Robinsons model, I explore mobilitys impact on class conflict in a society where the tax rate is not fixed. I demonstrate that if the tax rate is proportional to the population of the group in power relative to the total population of the society, then the effects of social mobility on class conflict are indeed ambiguous.Submitted: February 2002, Accepted: July 2003,I am grateful to an anonymous referee and Amihai Glazer for their comments. I would also like to thank Herschel Grossman for his help along the way. 相似文献

Based on ‘endogenous’ growth theory, the paper examines the effect of trade liberalization on long-run income per capita and economic growth in Turkey. Although the presumption must be that free trade has a beneficial effect on long run growth,
counter examples can also be found. This controversy increases the importance of empirical work in this area. Using the most
recent data we employ multivariate cointegration analysis to test the long run relationship among the variables in hand. In
a multivariate context, the effect of determinants such as increasing returns to scale, investment in human and physical capital
are also included in both theoretical and empirical works. Our causality evidence between the long run growth and a number
of indicators of trade liberalizations confirms the predictions of the ‘new growth theory’. However, the overall effect of
the possible breaks and/or policy change and unsustainability in the 1990s looks contradictory and deserves further investigation. 相似文献

This paper examines the economic and political conditions that influence peoples attitudes regarding a municipality break-up. The theoretical model predicts intra-municipal differences in tax bases, political preferences, and population size to affect the expected gain from secession. The predictions of the model are tested using data on local referenda about municipality partitioning in Sweden. The data support one of the three effects; voters in municipality parts that are wealthy compared to other parts of the same municipality are more positive to secession.Received: April 2003, Accepted: September 2003, JEL Classification Numbers:

Many structural relationships should be taken into account in any reasonable adjustment and updating process. These structural
relationships are mainly represented by ratios of different types, such as technical coefficients or the proportion of the
cell value in relation to its row or column total. We believe that in many cases (either because of lack of information or
when the time elapsed for the estimation of a social accounting matrix is not long enough to allow for any significant structural
change) the updating process should try to minimize the rela- tive deviation of the new coefficients from the initial ones
in a homogeneous way. This homogeneity would mean that the magnitude of this relative deviation is similar among the elements
of each row or column, therefore avoiding the concentration of the changes in particular cells of the SAM. In this work, we
propose some new adjustment criteria in order to obtain a more homogeneous relative adjustment of the structural coefficients.
These criteria combine the adjustment method proposed by Matuszewski et al. (1964) with other deviation functions. Each of
the adjustment criteria proposed leads to a nonlinear optimization problem which is reformulated as a linear program. We test
the usefulness of this proposal by comparing its results with the ones obtained by more standard approaches and we are able
to show that these approaches tend to produce a less homogeneous pattern of coefficient adjustment, under certain circumstances,
than the ones we put forward. 相似文献

In this paper, we estimate the impacts of product market competition and skill shortages on the productivity level performance of Canadian manufacturing firms. We use firms perceptions of their competitive environment from the Statistics Canada 1999 Survey of Innovation to measure product market competition and skill shortages. We argue in the paper that such perceptions are important for productivity level performance. After controlling for other factors, we find that product market competition has a positive impact on the performance of medium-sized and large-sized firms, and that skill shortages have a negative impact on the performance of small-sized and medium-sized firms.Jel Classification: L0, O0 相似文献

Christofides (2003) has given an improved modification of Warners (1965) pioneering randomized response (RR) technique in estimating an unknown proportion of people bearing a sensitive characteristic in a given community. As both these RR devices are shown to yield unbiased estimators based only on simple random sampling (SRS) with replacement (WR) but in practice samples are mostly taken with unequal selection probabilities without replacement (WOR), here we present methods of estimation when Christofides RR data are available from unequal probability samples. Warners (1965) RR device was earlier shown by Chaudhuri (2001) to be applicable in complex surveys. For completeness we present estimators for the variance of our estimator and also describe what to do if some people opt to divulge truths.This research is partially supported by CSIR grant No. 21(0539)/02/EMR-II 相似文献

Preference Anomalies,Preference Elicitation and the Discovered Preference Hypothesis 总被引:1,自引:1,他引:1
There is wide-ranging evidence, much of it deriving from economics experiments, of ‘anomalies’ in behaviour that challenge
standard preference theories. This paper explores the implications of these anomalies for preference elicitation methods.
Because methods that are used to inform public policy, such as contingent valuation, are based on standard preference theories,
their validity may be called into question by the anomaly data. However, on a new interpretation, these anomalies do not contradict
standard theory but are errors in stated preference that can be expected to disappear as people become more experienced in
relevant decision environments. We explore the evidence for this interpretation and what implications follow for preference
elicitation methodology.

The political economy of environmental policy favors the use of quantity-based instruments over price-based instruments (e.g.,
tradable permits over green taxes), at least in the United States. With cost uncertainty, however, there are clear efficiency
advantages to prices in cases where the marginal damages of emissions are relatively flat, such as with greenhouse gases.
The question arises, therefore, of whether one can design flexible quantity policies that mimic the behavior of price policies,
namely stable permit prices and abatement costs. We explore a number of “quantity-plus” policies that replicate the behavior
of a price policy through rules that adjust the effective permit cap for unexpectedly low or high costs. They do so without
necessitating any monetary exchanges between the government and the regulated firms, which can be a significant political
barrier to the use of price instruments. 相似文献

In this paper we examine whether cost–benefit analysis is anomaly-susceptible or anomaly-proof. To do this, we address four questions. These are, which anomalies, or problems seem most troublesome for CBA? What coping strategies does the analyst adopt to address these problems? Do these adaptation strategies create new problems? And finally, does adopting these strategies invalidate the results of CBA, or reduce the power of its advice? The anomalies we consider are (i) the observed differences between willingness to pay and willingness to accept compensation measures of value; (ii) valuation given information limits, preference uncertainty and preference construction; (iii) hypothetical market bias; (iv) risk perceptions; and (v) risk and preference reversals. We focus our discussion on the estimation of non-market environmental benefits and costs. 相似文献
