In the context of the proposed EU financial supervisory reforms, this paper focuses on the governance of the network of national supervisory banking agencies and the newly established Community supervisor (European Banking Authority, EBA). We assess to what extent lack of governance convergence nationally and with EBA could undermine the incentives for cooperation among supervisors. Convergence should particularly focus on (i) the issue of the presence of politicians on decision-making bodies; (ii) the need for clearly defining dismissal procedures of heads of supervision; (iii) autonomy from government in regulatory matters; (iv) supervisory autonomy in matters of licensing and withdrawing licenses; (iv) mechanisms for judicial accountability; (v) legal protection for supervisors handling in good faith. In the absence of full centralization of prudential supervision, early harmonization of national governance arrangements towards best practice would better align supervisors’ incentive structures and, hence, be beneficial for the effectiveness of European supervision.  相似文献

This article offers a tractable model of (oligopolistic) competition in differentiated product markets characterized by individual demand uncertainty. The main result shows that, in equilibrium, firms offer advance purchase discounts and that these discounts are larger than in the monopolistic benchmark. Competition reduces welfare by increasing the fraction of consumers who purchase in advance, that is, without (full) knowledge of their preferences.  相似文献

We formulate a two-period life cycle model of saving, labor supply, and human capital investment when individuals differ in their ability and initial wealth. Borrowing constraints result in sub-optimal choices for consumption and investments in human capital. We analyze optimal linear income taxes and education subsidies. The optimal income tax is shown to be positive—even in the absence of any redistributional concerns. A redistributive income tax relaxes borrowing constraints by redistributing resources from the unconstrained to the borrowing constrained stages of the life cycle. The income tax thus alleviates preexisting non-tax distortions in the capital market. Human capital is subsidized on a net basis in the absence of redistributional concerns. Education subsidies help to relax credit constraints and to reduce distortions from explicit and implicit taxes on human capital formation. When redistributional concerns are present, education is subsidized more if this helps to alleviate distortions on labor supply, but is subsidized less if education subsidies have a very regressive incidence. Simulations demonstrate that optimal income taxes are substantially higher when credit constraints are present. Education is generally subsidized on a net basis, and the more so if credit constraints are more severe.  相似文献

We compare intraday impacts of the release of Federal Reserve decision announcements and of Federal Open Market Committee minutes between 2004 and 2015 on 1,997 equity return and volatility series. We find that returns are unresponsive to either news release, but conditional volatility increases for both, manifesting immediately after each information release, and persisting for 30 minutes post‐announcement. These effects are larger for decisions than for minutes. On stratifying firms by trading intensity, we find most “high trading intensity” firms respond to these announcements, while “low trading intensity” firms are less affected. Our results show that traders respond, albeit differently, to both sets of information releases.  相似文献

We prove that, under very weak conditions, optimal financial products on complete markets are co-monotone with the reversed state price density. Optimality is meant in the sense of the maximization of an arbitrary preference model, e.g., expected utility theory or prospect theory. The proof is based on a result from transport theory. We apply the general result to specific situations, in particular the case of a market described by the Capital Asset Pricing Model or the Black–Scholes model, where we derive a generalization of the two-fund-separation theorem and give an extension to APT factor models and structured products with several underlyings. We use our results to derive a new approach to optimization in wealth management, based on a direct optimization of the return distribution of the portfolio. In particular, we show that optimal products can (essentially) be written as monotonic functions of the market return. We provide existence and nonexistence results for optimal products in this framework. Finally we apply our results to the study of bonus certificates, show that they are not optimal, and construct a cheaper product yielding the same return distribution.  相似文献

Performance measurements may stimulate employee initiatives to improve operational performance, especially when employees themselves participate in the development of their own departmental performance measures. Using the theory of planned behavior, we examine why this occurs in a beverage manufacturing company where we helped bottling line maintenance technicians develop measures about the results of their own work. Our analyses are based on qualitative data gathered at 156 meetings, 34 semi-structured interviews, quantitative performance data from the company's information systems, and quantitative questionnaire data. We found that the participatory development process increased employees’ attitude, perceived social pressure and perceived capability to take initiative. Moreover, the departmental performance improved when the jointly developed performance measures were put to use.  相似文献

The emergence of the gold standard has for a long time been viewed as inevitable. We analyze agents' expectations using the spread between gold and silver bonds issued by the Indian government. We find that bimetallism was credible until France surprised markets by suspending domestic operation of bimetallism, triggering a run away from silver. Thereafter, markets began demanding a premium to hold silver bonds, indicating their belief that silver would depreciate in the future as more countries moved on gold.  相似文献

We build a new class of discrete-time models that are relatively easy to estimate using returns and/or options. The distribution of returns is driven by two factors: dynamic volatility and dynamic jump intensity. Each factor has its own risk premium. The models significantly outperform standard models without jumps when estimated on S&P500 returns. We find very strong support for time-varying jump intensities. Compared to the risk premium on dynamic volatility, the risk premium on the dynamic jump intensity has a much larger impact on option prices. We confirm these findings using joint estimation on returns and large option samples.  相似文献
