Strategy-proof allocation when preferences are single-plateaued

Abstract. We consider private good economies with single-plateaued preferences. A solution selects for each preference profile a non-empty set of allocations. An agent strictly prefers a set of allocations to another set of allocations if and only if he strictly prefers any allocation in the first set to any in the second set according to his single-plateaued preference relation. We characterize the class of sequential-allotment solutions by essentially single-valuedness, Pareto-indifference, and coalitional stragety-proofness. These solutions are the Pareto-indifferent extensions of the solutions studied by Barberà et al. 1997. Received: 9 May 2000 / Accepted: 1 May 2001     

The productivity of transport infrastructure investment: A meta-analysis of empirical evidence

Investments in transport infrastructure have been widely used by decision makers to encourage economic growth, particularly during periods of economic downturn. There has been extensive research on the linkage between transport infrastructure and economic performance since the late 1980s, characterised by widely varying evidence. We conduct a meta-analysis of the empirical evidence on the output elasticity of transport infrastructure, based on a sample of 563 estimates obtained from 33 studies. Previous meta-analyses have focused on total public capital and hence cannot appropriately explain the wide variation in the productivity effect of transport infrastructure nor provide guidance to policymakers on the returns to investment in different types of transport infrastructure. Our results indicate that the existing estimates of the productivity effect of transport infrastructure can vary across main industry groups, tend to be higher for the US economy than for European countries, and are higher for roads compared to other modes of transport. The variation in the estimates of the output elasticity of transport is also explained by differences in the methods and data used in previous studies. Failing to control for unobserved heterogeneity and spurious associations tends to result in higher values, while failing to control for urbanisation and congestion levels leads to omitted variable bias. These findings can be used to inform future research on the choice of model specification and estimation and transport-related policy making.     

Does the World Economy Swing National Elections?*

Do voters reward national leaders who are more competent economic managers, or merely those who happen to be in power when the world economy booms? Using data from 268 democratic elections held between 1978 and 1999, I compare the effect of world growth (luck) and national growth relative to world growth (competence). Both matter, but the effect of luck is larger than the effect of competence. Voters are more likely to reward competence in countries that are richer and better educated; and there is some suggestive evidence that media penetration rates affect the returns to luck and competence.     

Global identification of risk preferences with revealed preference data

The concept of parameter identification (for a given specification) is differentiated from global identification (which specification is right). First-order conditions for production under risk are shown to admit many alternative specification pairs representing risk preferences and either perceived price risk, production risk, or the deterministic production structure. Imposing an arbitrary specification on any of the latter three determines which risk preference specification fits a given dataset, undermining global identification even when parameter identification is suggested by typical statistics. This lack of identification is not relaxed by increasing the number of observations. Critical implications for estimation of mean-variance specifications are derived.     

Do Firms Increase Productivity in Order to Become Exporters?*

Recent studies find that exporters are more productive than non‐exporters and that entry into exporting does not increase firms’ productivity. Thus, firms self‐select into foreign markets. This paper examines productivity before entry into exporting. Using Chilean plant‐level data, we find that productivity and investment increase before plants begin to export. Moreover, productivity of entrants to exporting, but not that of non‐exporters and exporters, increases in response to increases in foreign income, before entry but not after that. The results suggest that the productivity advantage of future exporters may be the result of firms increasing their productivity in order to export.     

Sprumont's characterization of the uniform rule when all single-peaked preferences are admissible

Sprumont (1991) has established that the only allocation rule for the division problem that is strategy-proof, efficient, and anonymous is the uniform rule when the domain is the set of all possible profiles of continuous single-peaked preferences. Sprumont's characterization of the uniform rule is shown to hold on any larger domain of single-peaked preferences. Received: 15 December 1998 / Accepted: 12 April 1999     

Climate cooperation from Kyoto to Paris: What can be learnt from the CDM experience?

The mitigation of greenhouse gas concentration has become a first-order issue for decision making in environmental sustainability. Countries can meet their mitigation commitments and environmental objectives through multiple instruments. A key role is played by cooperative mechanisms, such as the Clean Development Mechanism (CDM), under the Kyoto Protocol, and a similar mechanism established by the Paris Agreement (Art. 6), whose implementation rules are still under negotiation. However, another form of cooperation was already established under the different framework of the Official Development Assistance (ODA), potentially sharing abatement purposes. This paper aims to compare the mitigation actions implemented either as CDM or ODA projects. We conduct a multi-criteria econometric analysis, based on an originally created, harmonised dataset that merges renewable energy CDM projects and comparable ODA projects to investigate the role of the institutional framework in influencing the effectiveness of reducing emissions worldwide. Results show that the Kyoto Protocol had a positive impact in terms of cost-effectiveness for renewable energy projects and that it stimulated policy actions for environmental sustainability. Accordingly, in view of the implementation of Article 6 of the Paris Agreement, it is extremely important both to look to the past to draw lessons from Kyoto's successes and failures and to apply multi-criteria decision-making approaches for the design of environmental policies.     

Growth, development and natural resources: New evidence using a heterogeneous panel analysis

This paper explores whether natural resource abundance is a curse or a blessing. To do so, we firstly develop a theory consistent econometric model, in which we show that there is a long run relationship between real income, the investment rate, and the real value of oil production. Secondly, we investigate the long-run (level) impacts of natural resource abundance on domestic output as well as the short-run (growth) effects. Thirdly, we explicitly recognize that there is a substantial cross-sectional dependence and cross-country heterogeneity in our sample, which covers 53 oil exporting and importing countries with very different historical and institutional backgrounds, and adopt the non-stationary panel methodologies developed by Pesaran (2006) and Pedroni (2000) for estimation. Our results, using the real value of oil production, rent or reserves as a proxy for resource endowment, reveal that oil abundance has a positive effect on both income levels and economic growth. While we accept that oil rich countries could benefit more from their natural wealth by adopting growth and welfare enhancing policies and institutions, we challenge the common view that oil abundance affects economic growth negatively.     

R&D and productivity: A broad cross-section cross-country look

The empirical literature on R&D and productivity has shown that there is indeed a positive influence of R&D investment on output growth. However, the exact relation depends to a large extent on the approach chosen (i.e., functional form). Because most studies concentrate on a limited number of countries or sectors and use their own specific methodology, comparison is difficult. This paper aims at providing a broad overview of cross-country and cross-sector differences in the relation between (direct) R&D and output growth, using a common methodology, so that comparison is easier. The functional form used is a translog production function, which is applied to data for 15 manufacturing sectors and 9 principal OECD countries.     

Scarcity, regulation and endogenous technical progress

This paper studies to which extent a firm using a scarce resource input and facing environmental regulation can still manage to have a sustainable growth of output and profits. The firm has a vintage capital technology with two complementary factors, capital and a resource input subject to quota, the latter being increasingly scarce through an exogenously rising price. The firm can scrap obsolete capital and invest in adoptive and/or innovative R&D resource-saving activities. Within this realistic framework, we first characterize long-term growth regimes driven by scarcity (induced-innovation) vs. long-term growth regimes driven by quota regulation (Porter-like innovation). More importantly, we study the interaction between scarcity and quota regulation. In particular, we show that there exists a threshold level for the growth rate of the resource price above which the Porter mechanism is killed while the scarcity-induced growth regime may emerge. Symmetrically, we also find that there must exist a threshold value for the environmental quota under which the growth regime induced by scarcity vanishes while the Porter-like growth regime may survive.     

Growth,deficits and uncertainty: Theoretical aspects and empirical evidence from a panel of 27 countries

We examine the relationship between fiscal deficits and per-capita income growth in a panel of 27 European countries, allowing for perceived risks, in terms of fiscal sustainability, associated with additional government spending. Such risks are proxied by the conditional variability of manufacturing production and stock market returns and by the unconditional variability of two survey-based economic-sentiment indicators. To help clarifying how fiscal variables impact on growth and to provide a point of reference for the interpretation of the empirical results a structural growth model is first identified. We find evidence of an asymmetric relationship, in that fiscal deficits give rise to adverse growth effects if they coincide with high uncertainty regarding the prospects of the economy and no significant negative growth effects in the low-uncertainty case.     

Does bond market development enhance the banking sector’s efficiency in resource allocation? Industry-level evidence from Korea

Korea’s financial system used to be bank-based, with banks playing the leading role in financing corporations. As highlighted by Park et al. (2019), however, bond markets have developed rapidly in Korea and other Asian countries. The corporate bond market competes with banks as a source of finance for large borrowers. As such, bond markets may affect banking sector operation, a process known as disintermediation. In this paper, we examine whether bond market development improves the efficiency of resource allocation in Korean bank lending. We propose two channels through which bond market development affects the efficiency of bank lending. Since the two channels have opposing effects on the efficiency of banking, the issue must be settled by empirical analysis. We find that bank loans are much less efficient than bond financing in allocating resources across industries. Furthermore, banks are particularly inefficient in resource allocation in industries that rely more on bond financing. This suggests that competition from bond financing does not improve allocative efficiency of bank loans.     

Explaining the East Asia miracle: The role of urbanization

Defying the law of diminishing marginal returns, many countries experienced high rates of investment for a prolonged period of time during their take-offs. This paper represents a first attempt to explain this contradiction from the perspective of urbanization. Urbanization provides opportunities for investment and helps moderate the capital/labor ratio in the urban sector. In particular, it promotes knowledge accumulation through “learning by doing”. This can explain why the law of diminishing marginal returns to capital is not applicable to economies in the early period of their catching-up. More specifically, we construct a two-sector general equilibrium model incorporating urbanization and “learning by doing”, predicting that in the presence of urbanization, as long as the “learning by doing” effect is sufficiently large, capital return will depict an inverted U-shape as capital accumulates or urbanization proceeds. Empirical evidence from China confirms the theoretical prediction.
