No arbitrage and closure results for trading cones with transaction costs

In this paper, we consider trading with proportional transaction costs as in Schachermayer’s paper (Schachermayer in Math. Finance 14:19–48, 2004). We give a necessary and sufficient condition for ${\mathcal{A}}$ , the cone of claims attainable from zero endowment, to be closed. Then we show how to define a revised set of trading prices in such a way that, firstly, the corresponding cone of claims attainable for zero endowment, ${\tilde{ {\mathcal{A}}}}$ , does obey the fundamental theorem of asset pricing and, secondly, if ${\tilde{ {\mathcal{A}}}}$ is arbitrage-free then it is the closure of ${\mathcal{A}}$ . We then conclude by showing how to represent claims

An examination of the relationship of governance structure and performance: Evidence from banking companies in Bangladesh

Corporate governance has become increasingly important in developed and developing countries just after a series of corporate scandals and failures in a number of countries. Corporate governance structure is often viewed as a means of corporate success despite prior studies reveal mixed, somewhere conflicting and ambiguous, and somewhere no relationship between governance structure and performance. This study empirically investigates the relationship between corporate governance mechanisms and financial performance of listed banking companies in Bangladesh by using two multiple regression models. The study reveals that a good number of companies do not comply with the regulatory requirements indicating remarkable shortfall in corporate governance practice. The companies are run by the professional managers having no duality and no ownership interest for which they are compensated by high remuneration to curb agency conflict. Apart from some inconsistent relationship between some corporate variables, the corporate governance mechanisms do not appear to have significant relationship with financial performances. The findings reveal an insignificant negative impact or somewhere no impact of independent directors and non-independent non-executive directors on the level of performance that strongly support the concept that the managers are essentially worthy of trust and earn returns for the owners as claimed by stewardship theory. The study provides support for the view that while much emphasis on corporate governance mechanisms is necessary to safeguard the interest of stakeholders; corporate governance on its own, as a set of codes or standards for corporate conformance, cannot make a company successful. Companies need to balance corporate governance mechanisms with performance by adopting strategic decision and risk management with the efficient utilization of the organization’s resources

The Real-Time Predictive Content of Asset Price Bubbles for Macro Forecasts

This paper contributes to the debate of whether central banks can \lean against the wind" of emerging stock or house price bubbles. Against this background, the paper evaluates if new advances in real-time bubble detection, as brought forward by Phillips et al. (2011), can timely detect bubble emergences and collapses. Building on simulations, the paper shows that the detection capabilities of all indicators are sensitive to their exact specifications and to the characteristics of the bubbles in the sample. Therefore, the paper suggests a combination approach of different bubble indicators which helps to account for the uncertainty around start and end dates of asset price bubbles. Additionally, the paper then investigates if the individual and combination indicators carry predictive content for inflation and output growth when the real-time availability of all variables is taken into account. It finds that a combination indicator is best suited to uncover the most common stock and house price bubbles in the U.S. and shows that this indicator improves output forecasts

Speculative Price Bubbles in Urban Housing Markets in Germany

The surge in the German house prices starting in 2010 raised fears about the emergence of a speculative bubble. Given a local nature of housing markets, it is not clear to what extent the bubble, if any, is spread across different cities. In this paper, we test for speculative house price bubbles in 127 large German cities over the last 20 years. Along with testing bubbles for each city separately, we apply two new testing approaches: a panel data and principal components version of explosive root tests. We define bubble as an explosive growth of prices that is not supported by the rent increase. Therefore, to check for the existence of bubbles, we examine prices, rents, and price-to-rent ratios. We find evidence for explosive price increases in many cities, especially for the case of newly built housing. However, only in few urban housing markets prices decouple from their fundamental values. On the national level, we do not see evidence for speculative price movements. Overall, we find that the danger of a build-up of a speculative price bubble in the German housing market is rather moderate

Financial Constraints and the Cyclicality of R&D Investment: Evidence from Slovenia

This paper uses firm level data to show how R&D investment responds to shocks in sales growth in credit constrained firms. A credit constrained firm has to rely on its cash flow and borrowing capacity to survive its short-run liquidity shock when hit by a negative shock. This reduces the possibility for further borrowing in order to invest in non-tangible long tfirm R&D, hence a negative shock should hit R&D investments more in firms that are more credit constrained. We find that in financially constrained firms sales growth is positively associated with R&D investment, suggesting procyclical behavior of R&D investment in credit constrained firms. In contrast, we find that in firms with no financial constraints R&D investment is negatively correlated with sales growth, suggesting countercyclical behavior of R&D, consistent with the Schumpeterian idea of restructuring. Furthfirmore, we find that the firm level response in R&D investment to sales growth is stronger in firms that are more financially dependent, such as firms that are no part of a multinational, firms not receiving subsidies or firms with less collateral

Lessons from the New Deal: Did the New Deal Prolong Or Worsen the Great Depression?

Since the current recession began in December 2007, New Deal legislation and its effectiveness have been at the center of a lively debate in Washington. This paper emphasizes some key facts about two kinds of policy that were important during the Great Depression and have since become the focus of criticism by new New Deal critics: (1) regulatory and labor relations legislation, and (2) government spending and taxation. We argue that initiatives in these policy areas probably did not slow economic growth or worsen the unemployment problem from 1933 to 1939, as claimed by a number of economists in academic papers, in the popular press, and elsewhere. To substantiate our case, we cite some important economic benefits of New Deal-era laws in the two controversial policy areas noted above. In fact, we suggest that the New Deal provided effective medicine for the Depression, though fiscal policy was not sufficiently countercyclical to conquer mass unemployment and prevent the recession of 1937-38; 1933's National Industrial Recovery Act was badly flawed and poorly administered, and the help provided by the National Labor Relations Act of 1935 came too late to have a big effect on the recovery
