The determinants of individual, voluntary climate action (VCA) in combating climate change and its potential scale are frequently debated in public but largely underresearched. We provide estimates of the willingness to individually reduce EU greenhouse gas emissions by one ton, using the European Union Emissions Trading Scheme. Estimates are derived from an online field experiment with a large, highly heterogenous, and Internet-representative sample of voting-aged Germans. Jointly estimating willingness to pay (WTP), non-indifference to VCA, and prior knowledge, we uncover important determinants of preferences for VCA, such as education, the information structure among the population, and exogenous environmental conditions. 相似文献

A key tax policy parameter that has received much attention in the international literature, but about which there is substantial uncertainty, is the overall elasticity of taxable income. The size of this parameter is central to the formulation of tax and transfer policy, as well as for the study of the welfare implications of tax decisions. This paper uses a panel of individual tax returns for the period 2009–2013 and the phenomenon of “bracket creep” to construct instrumental variable estimates of the sensitivity of income to changes in tax rates. Estimates suggest that the overall elasticity of taxable income is approximately 0.3, while that of broad income is significantly lower. The overall response is primarily driven by the elastic response of taxable income for high‐income earners, who have an elasticity of closer to 0.4. Using the elasticity estimates within an optimal tax framework, it is determined that the optimal marginal tax rate for the top 10% of income earners is broadly in line with the current income tax schedule. However, results also suggest that there is little scope for raising marginal rates on high‐income earners further without inducing a negative revenue response. 相似文献

This contribution investigates the efficiency of water suppliers in rural areas of East and West Germany. A non-radial measure
of input specific allocative inefficiency is used to reduce the distributional dependency with respect to the inefficiency
parameters. It is based on the demand system of a flexible cost function for the variable inputs labour, energy and chemicals
modelled by applying a modified symmetric generalized McFadden functional form. Concavity restrictions, as required by economic
theory, are imposed. The analysis reveals that efforts towards increasing suppliers’ allocative efficiency should focus on
the relatively inefficient usage of the input chemicals. The input specific allocative model specification was found to be
superior to the overall allocative specification.

One of the main goals of the European Union, laid down, inter alia, in the Lisbon Strategy and in the “Europe 2020” Strategy, is to raise employment. One important means of supporting the
creation of new jobs is to increase competition. In this paper, it is shown that on average the mark-up, i.e. the deviation
of prices from marginal cost in the euro area still exceeds the levels observed in the UK and in the US. After completion
of the Single Market Programme in 1993, the mark-up has declined in the euro area and even more in the UK. Nevertheless, there
is a strong cross-country variation between Member States, with a particularly high mark-up ratio found for Italy. Panel estimations
show that total factor productivity growth, labour productivity growth and the labour market performance in the euro area
could be improved by reducing the mark-up. This could be achieved by a proper institutional design. More competition could
indeed improve the macroeconomic performance. 相似文献

This article explores project management offices (PMOs) through community of practice theory. Preliminary results from a national health care case study are used to confirm the legitimacy of this approach. Today's knowledge‐based economy calls for mechanisms to share knowledge. The issue of making more with less is at stake in order to reuse good practices, support innovative practice, and prevent the reinvention of the wheel. Members of these communities are at the heart of the learning process. The originality of this research is that it sheds light on PMOs in a new theoretical perspective within the field of knowledge management. 相似文献

We investigate the general structure of optimal investment and consumption with small proportional transaction costs. For a safe asset and a risky asset with general continuous dynamics, traded with random and time‐varying but small transaction costs, we derive simple formal asymptotics for the optimal policy and welfare. These reveal the roles of the investors' preferences as well as the market and cost dynamics, and also lead to a fully dynamic model for the implied trading volume. In frictionless models that can be solved in closed form, explicit formulas for the leading‐order corrections due to small transaction costs are obtained. 相似文献

Economists’ faith that variable exchange rates benevolently equilibrate has been empirically disconfirmed. That faith is here tackled at its theoretical core with an exchange rate model that although ultra abstract, includes the undeniable fundamentals of market power and differential goals of central bankers and large-scale private players. It permits a game theoretic analysis under the assumption that all agents maximize their payoffs. The paper then relaxes
the assumption of maximising agents, allowing for a more complex and thus realistic second version of the model that is interpretable
within SKAT, the Stages of Knowledge Ahead Theory of risk and uncertainty. In an experimental setting, this second version
of the model points to: a) the inability of agents in central banks, governments and the private real and financial sectors
to operate in maximising ways; b) destructive central bank conflict; and c) the widely discrepant outcomes arising from the
dynamics of individual personality differences. The paper’s theoretical and empirical findings thus both point to the merits
of a single world currency. 相似文献

This paper analyses optimal taxation of foreign profits using a model with heterogeneous multinational firms that serve a foreign market through exports or foreign direct investment (FDI). If a firm switches from exporting to FDI, domestic activity and tax payments may decrease, stay constant or even rise because of intra‐firm trade. It turns out that, in contrast to recent claims, in all three cases, the optimal tax system implies full taxation after deduction of foreign tax payments. If the country accounts for the effects of its policy on the foreign price level, the case for taxing foreign income becomes even stronger. However, the globally optimal tax system may require exemption of foreign income from tax. 相似文献
