The tactical and strategic value of hedge fund strategies: a cointegration approach

This paper analyzes long-term comovements between hedge fund strategies and traditional asset classes using multivariate cointegration methodology. Since cointegrated assets are tied together over the long run, a portfolio consisting of these assets will have lower long-term volatility. Thus, if the presence of cointegration lowers uncertainty, risk-averse investors should prefer assets that are cointegrated. Long-term (passive) investors can benefit from the knowledge of cointegrating relationships, while the built-in error correction mechanism allows active asset managers to anticipate short-run price movements. The empirical results indicate there is a long-run relationship between specific hedge fund strategies and traditional financial assets. Thus, the benefits of different hedge fund strategies are much less than suggested by correlation analysis and portfolio optimization. However, certain strategies combined with specific stock market segments offer portfolio managers adequate diversification potential, especially in the framework of tactical asset allocation.

Negative externalities on property values resulting from water impairment: The case of the Pigeon River Watershed

The objective of this research was to determine whether willingness to bear the negative externality from water quality impairment differs between those who do and those who do not receive economic benefit from the impairment source. Differences were tested using a hedonic analysis of ambient water quality in two discrete housing markets in the Pigeon River Watershed, which have been polluted by the operation of a paper mill. The results suggest that North Carolina residents residing in subwatersheds with impaired portions of the Pigeon River, who experience economic benefit from the paper mill in addition to its harmful effects on water quality, do perceive the pollution as a negative externality. In contrast, the effects of both the degraded river and its contributing streams on property values are perceived as negative externalities by watershed residents in Tennessee who experience only harmful effects from the pollution. Differences in willingness to bear the water-impairment externality were not indicated by variables representing view of and proximity to impaired water bodies. The results suggest that the perception of water quality to which property owners implicitly apply value should be considered when establishing water-quality regulations.     

Should we delight the customer?

Critics have suggested that delighting the customer “raises the bar” of customer expectations, making it more difficult to satisfy the customer in the next purchase cycle and hurting the firm in the long run. The authors explore this issue by using a mathematical model of delight, based on assumptions gathered from the customer satisfaction literature. Although delighting the customer heightens repurchase expectations and makes satisfying the customer more difficult in the future, and the delighting firm is injured by raised customer expectations, the (nondelighting) competition is hurt worse through customer attrition to the delighting firm. If customers forget delighting incidents to some degree from occasion to occasion, the delighting firm suffers if it is in a position to take customers from the competition. If taking customers from the competition is difficult, the delighting firm actually benefits from customer forgetting, because the same delighting experience can be repeated again, with the same effect.

Backup strategy for robots’ failures in an automotive assembly system

Automotive assembly lines are often characterized by robots’ failures that may result in stoppages of the lines and manual backup of tasks. The phenomena tend to impair throughput rate and products’ quality. This paper presents a backup strategy in which working robots perform tasks of failed robots. The proposed Mixed-Integer Linear-Programming based approach minimizes the throughput loss by utilizing the robots’ redundancy in the system. Two algorithms are developed to comply with stochastic conditions of a real-world environment. The performance of these algorithms is compared with several heuristics, and the downstream-backup based algorithm is found superior to all other methods.     

Sustainability and consumption

We consider the implications of the three pillars of sustainability (environment, economy and social justice) on consumption in a wealthy country. Building a theoretical model that includes consumers, business, government, the environment, and economic and political relations between nations, we explore how sustainability should affect the consumption behavior of consumers, charitable aid to poorer countries, and responsible environmental practices by businesses. Our model enables us to provide normative implications for consumers, society and business. Importantly, we assume that all stakeholders will optimize their self-interest, and that altruism will only partly explain behavior consistent with sustainability. Among the more non-obvious findings are that (1) the poorer the poor countries are, the less the rich countries should consume, (2) the more sensitive the global political climate is to economic inequity between the rich and poor nations, the less the rich countries should consume, and (3) if aid to poor countries is effective enough, then the more materialistic the society is, the more charitable aid it should give. We also confirm a number of more intuitive findings, such as that business should use more green technology as the taxes on pollution and/or efficiency of green technology increase, and the more resource-intensive consumption is, the less consumers should consume. Taken as a whole, the findings imply that societal consumption patterns should be sensitive to aspects of environmental impact and social justice, even if altruistic motivations are absent.     

Rekommunalisierung versus Neukonzessionierung der Energieversorgung

The current trend back to municipal utilities (??remunicipalisation??) in the German energy system shows very different approaches and variants in the real cases. Converting the distribution network from privately-owned distribution companies to municipally-owned entities often forms the starting point of such restructuring processes. Ecological or regional development motivations are at the forefront of public debates. The authors emphasize the importance of energy economic aspects of this problem. Advantages and disadvantages of remunicipalisation projects depend strongly on the specific regional circumstances. Important factors are the potentials for cooperation and expansion of the business activities. Moreover, the price which has to be paid for taking over the network infrastructure has to be taken into account as the decisive parameter: The price for buying or renting the network and the possible revenues on the backdrop of incentive-based regulation define the economic viability for the municipality. Many of the often heard arguments pro remunicipalisation, such as the objective of decentralized energy supply, labour effects and municipal contributions to climate protection, do not fully convince in the end; as well the fiscal status of many municipalities in Germany is severe. Nonetheless remunicipalisation must not be rejected in general because there is no general proof for welfare losses resulting from these projects. In fact, it depends mainly on local influencing factors to what extent municipalities should be or become active in the field of energy supply. Among the most important aspects the preferences of the citizens, the environmental and political aims of the municipality (so far they are defined) and the available resources of the municipal decision making persons and bodies must be mentioned. However, in economic terms the leeway for the municipality remains restricted by the costs of operating the network and tariff regulation.     

The influence of religious commitment on consumer perceptions of closed-on-Sunday policies: an exploratory study of Chick-fil-A in the southern United States

Many businesses operate long hours that often include nights and weekends to accommodate consumers. However, a few businesses maintain a closed-on-Sunday policy and do so while still operating successfully although closed-on-Sunday policies mean forgoing potential sales hours. As most Christian faiths consider the Sabbath as a day of rest, an oft-used rationalization for the success of businesses maintaining this policy is that they must be supported by consumers with strong religious beliefs, who appreciate the message sent by the company and as a result perceive the company favorably. The purpose of this paper was to investigate whether consumers' religious commitment influences their ethical judgment of a company's closed-on-Sunday policy and to determine whether this ethical judgment impacts a company's corporate or brand image and consumer loyalty intentions. The results suggest that consumers with higher levels of intra-personal religious commitment are more likely to hold favorable ethical judgments of closed-on-Sunday corporate policies. In addition, favorable ethical judgments of closed-on-Sunday corporate policies are likely to positively influence corporate image. A more positive corporate image ultimately results in higher consumer loyalty intentions.     

Detecting hot and cold cycles using a Markov regime switching model—Evidence from the Chinese A-share IPO market

This paper focuses on detecting hot and cold IPO cycles in the Chinese A-share market using a Markov regime switching model. We introduce a set of observations to measure IPO activities, which include numbers of IPOs issued, levels of underpricing, market conditions and duration time from prospectus and listing, and thus establish a model to estimate these activities' average performance in hot and cold periods respectively. It is found that a hot period is related with an abundant supply of IPOs, high levels of underpricing, positive market conditions and short waiting time to listing after prospectus issue. Further, this paper depicts the turning points of hot and cold periods across the period from 1994 to 2005 for each observation. The cycles detected by the number of IPOs per month are the benchmark and then these cycles' robustness is tested by the other observations.     

The external and domestic side of macroeconomic adjustment in China

This paper sheds new light on the external and domestic dimension of China’s exchange rate policy. It presents an open-economy model to analyse the macroeconomic adjustment process in China under both flexible and fixed exchange rate regimes. The model-based results indicate that persistent current account surpluses in China cannot be rationalized, under general circumstances, by the occurrence of permanent technology or labour supply shocks. As a result, to understand the macroeconomic adjustment process in China it is necessary to mimic the effects of potential inefficiencies, which induce the subdued response of domestic absorption to permanent income shocks, thereby causing the observed positive unconditional correlation of the trade balance and output. The paper argues that these inefficiencies can be potentially seen as a by-product of the fixed exchange rate regime, and can be approximated by a stochastic tax on domestic consumption or a time-varying transaction cost technology related to money holdings. Our results indicate that a fixed exchange rate regime with financial market distortions, as defined above, might induce negative effects on GDP growth in the medium term compared with a more flexible exchange rate regime.     

A Framework for Assessing Global Imbalances1

Since the mid‐1990s and prior to the financial crisis external balances of systemically important economies widened significantly. This paper takes a long‐run perspective and reviews the main determinants of widening global imbalances. To this aim, we first provide a set of newly derived statistical measures: while large external imbalances are not new in economic history, their persistence, their concentration on one economy (the United States) and the specific role of emerging market economies make the present episode rather unique. Second, we argue that the observed pattern of imbalances can be mostly understood as a result of various structural changes in the global economy, which have allowed a widening trend of external positions. Three main features set the most recent period apart from past episodes of growing external imbalances: (i) the emergence of new players, in particular emerging market economies such as China and India, which are quickly catching up with the advanced economies; (ii) an unprecedented wave of financial globalisation, with more integrated global financial markets and increasing opportunities for international portfolio diversification, also characterised by considerable asymmetries in the level of market completeness across countries; and (iii) the favourable global macroeconomic and financial environment, with record high global growth rates in recent years, low financial market volatility and easy global financing conditions over a long period of time, running until the outburst of the financial crisis during the summer of 2007. These structural changes that have been supplemented by cyclical or policy‐induced factors ultimately facilitated the sudden, disorderly unwinding of global imbalances that is reflected in the current financial crisis.
