In this paper, we examine under which conditions privatization is an effective means to develop local stock markets for a panel of 61 countries over the last twenty four years. By addressing the endogeneity between privatization and stock market development, we show for the 1980-98 period that the initial legal environment is a significant contemporary determinant of stock market development, while privatization is not. When we examine the dynamics of privatization in interaction with the legal environment, we find that privatization has a two-year-lagged effect on stock market development in emerging markets, and a one-year-lagged effect in developed countries. Results for the 1999-2003 period seem to be largely affected by the global crash that followed the Asian crisis. 相似文献

Creativity is an original cognitive ability and problem solving process which enables individuals to use their intelligence in a way that is unique and directed toward coming up with a product. Architectural education is one of the fields in which human creativity has been exhibited; because, it can be defined as a design study that correlates with other disciplines: social sciences, management, history, operational research, philosophy, graphic design, math and etc. These features which distinguish architecture from other disciplines ascribe different kind of responsibilities for architectural education; since beside technical and professional skills, an architect must have imagination and to be creative at many levels. Thus, this research aims at proving that students can be trained in creative thinking via acquiring specific skills and systematic techniques, which directly acts on design product. The study methodology depends on the concept of experimental research that targets at exposing students to creative problem solving experience via carrying out a creative training course that concerns “Consequential Creativity”. That experiment examined the potentiality of enhancing the students’ ability of viewing problems in non-traditional perspectives that counts on the systematic procedures of problem solving. Tools for assessment before and after training have been implemented. The Experiment findings proved that the students’ creative thinking skill has been clearly improved after attending the course. Therefore, training in creative thinking can be considered as independent courses or within specific architectural curricula. 相似文献

In this article we explain how Islamic banks (IBs) maximize profitability in the presence of costly religiosity. Because of strong competition between IBs and conventional banks (CBs), a unique equilibrium emerges that affects the IB pricing structure. We propose a new model that identifies the optimal rate on the asset and liability sides of IBs. It shows that the financial products offered by IBs are not an exogenous function of religiosity; instead, they are endogenously determined by the nature of market forces in which IBs are operating. We show that in the presence of costly religiosity and competition, the rates of both converge. Moreover, the competitive pricing mechanism induces IBs to structure their asset- and liability-side financial products (particularly Murabaha) with a risk profile similar to that of the CB loan system. This article empirically supports the theoretical propositions by using data from 17 Muslim majority countries where both IBs and CBs coexist from 2000 to 2015. We find that, holding other factors of bank returns constant, competition significantly affects IB asset- and liability-side returns. The analysis also reveals that because of increasing competition between IBs and CBs, the market power of IBs has significantly declined over time. 相似文献

We present a simulation-and-regression method for solving dynamic portfolio optimization problems in the presence of general transaction costs, liquidity costs and market impact. This method extends the classical least squares Monte Carlo algorithm to incorporate switching costs, corresponding to transaction costs and transient liquidity costs, as well as multiple endogenous state variables, namely the portfolio value and the asset prices subject to permanent market impact. To handle endogenous state variables, we adapt a control randomization approach to portfolio optimization problems and further improve the numerical accuracy of this technique for the case of discrete controls. We validate our modified numerical method by solving a realistic cash-and-stock portfolio with a power-law liquidity model. We identify the certainty equivalent losses associated with ignoring liquidity effects, and illustrate how our dynamic optimization method protects the investor's capital under illiquid market conditions. Lastly, we analyze, under different liquidity conditions, the sensitivities of certainty equivalent returns and optimal allocations with respect to trading volume, stock price volatility, initial investment amount, risk aversion level and investment horizon. 相似文献

Speeches are an important vehicle for central bankers to convey individual views on the preferred policy stance. In this article, we employ an automated text linguistic approach to create an indicator that measures the tone of the 1,618 speeches delivered by members of the Governing Council (GC) during the period 1999M1–2014M4. We then relate this variable to euro area and national macroeconomic forecasts. Our key findings are as follows. First, inflation and growth expectations have a positive and significant impact on the hawkishness of a speech. Second, different growth expectations across the euro area and different preferences significantly explain discrepancies across speakers. Third, the voiced preferences of presidents of the national central banks (NCBs) largely coincide with the level of independence their central banks had at the time of the Maastricht Treaty. However, in general, there are not much differences between members of the Executive Board and the NCB presidents. Fourth, we find some evidence that central bankers adjust the gist of their speeches depending on whether they talk at home or abroad and before or after a GC meeting. Finally, differences in central banker preferences are the key source of variation in their speeches before the financial crisis. 相似文献

This paper focuses on the effects of the Fed’s monetary policy on stock and bond returns co-movement and their implications to risk-based asset allocation. Using a regime-switching model that controls for the economic effects of monetary policy we identify three co-movement regimes. We document that risk-based portfolio strategies poorly perform in the low correlation regime which features inflation shocks. We find outperformance evidence under the negative correlation regime with a high stock market risk and a very accommodating Fed policy. Less effectiveness is demonstrated under the positive correlation regime where bonds are regarded as risky assets and interest rate volatility is fueled by monetary policy. 相似文献

Through a textual analysis of national newspaper articles covering European central bankers’ statements and policy decisions from 1999 to 2011, I derive the concerns expressed by national media in the Economic and Monetary Union (EMU). I consider these concerns as a benchmark for national preferences, and thus for the preferences of national central bankers in the EMU. I also test the existence of groups of national media (i.e., national publics) according to their shared expressed concerns. The results show that in the euro zone, similar concerns are shared by different country groups, corresponding to a group of countries from Northern Europe (Belgium, Finland, and the Netherlands), Southern Europe (Spain and Portugal), and the Periphery (Italy, Greece, and Ireland), but that there are two isolated countries (France and Germany), whose newspapers do not share the issues raised by the rest of the European newspapers. This approach provides further insights into the potential heterogeneity of the European central bankers inside the Governing Council of the ECB in terms of policy preferences. 相似文献

We investigate the relation between the private benefits' extraction by the initial controlling shareholder and the likelihood of the change of control post‐initial public offering (IPO) in France. We find that (a) in a weak investor protection context, the initial controlling shareholder with high private benefits of control is less likely to relinquish control 5‐years post‐IPO. (b) The initial controlling shareholder extracts private benefits of control through high voting rights and when the founder is involved in control at IPO. (c) Family controlling shareholders are less likely to end up with change of control post‐IPO than nonfamily ones. Such behavior is more pronounced with substantial voting rights, when the founder is in control and when the founder or his heir is an executive director. High private benefits of control contribute therefore to foster the survival of the initial controlling shareholder post‐IPO. Our findings are robust even after using alternative proxies of private benefits of control and also after running a survival analysis. 相似文献
