The day-of-the-week effect revisited: international evidence

The aim of this study is to determine whether the DOW effect still exists, and to evaluate empirically the explanations of the DOW effect for international equity markets. Evaluating 51 markets in 33 countries for the period between January 2000 and December 2007, reveals that the DOW effect persists for a significant proportion of equity markets. Evaluating open-to-close returns, liquidity, size effect and possible spill-over effects, the DOW effect can be explained for almost of all the exchanges. Individual stock analysis, covering 37,631 stocks traded in 51 equity markets shows that a DOW effect in returns exists for a statistically significant proportion of individual stocks in almost all of the markets in the study. Even markets without a market-level DOW effect contain a surprisingly large proportion of stocks with individual-level DOW effects. Interestingly, this proportion is only marginally lower than that which is found in markets with a market-level DOW effect.     

Inventory management with advance supply information

We consider a single stage inventory system with stochastic capacity. The manager receives forecasts from the upstream source about future capacity availability within an information horizon, referred to as “advance supply information”. We study two main questions: (i) How can advance supply information be utilized when making replenishment decisions? (ii) What is the value of such information sharing, compared to a fixed base-stock policy? We show that state-dependent base-stock policies are optimal. We develop easily computable and implementable heuristic policies. We numerically test the accuracy of the approximations and analyze the value of collaboration under various business scenarios.     

Inter-country distancing,globalisation and the coronavirus pandemic

Originating in China, the coronavirus has reached the world at different speeds and levels of strength. This paper provides an initial understanding of some driving factors and their consequences. Since transmission requires people, the human factor behind globalisation is essential. Globalisation, a major force behind global well-being and equality, is highly associated with this factor. The analysis investigates the impact globalisation has on the speed of initial transmission to a country and on the scale of initial infections in the context of other driving factors. Our cross-country analysis finds that measures of globalisation are positively related to the spread of the virus, both in speed and in scale. However, the study also finds that globalised countries are better equipped to keep fatality rates low. The conclusion is not to reduce globalisation to avoid pandemics, but to better monitor the human factor at the outbreak and mobilise collaboration forces to curtail diseases.     

Identifying Participants in a Price-fixing Conspiracy: Output & Market Share Tests Reexamined

If there is a cartel agreement among a subset of firms in an industry, it should be predicted that all firms in that industry will increase prices. Nevertheless, industry prices alone should not indicate that a particular firm is guilty of that conspiracy. According to the output test and its market share variant – proposed by Blair and Romano – if the output or the market share of the firm that claims to be innocent in the collusive activity rises in response to the price increase, that firm's claim should be accepted as true. Using a collusive variant of the dominant firm model, this paper shows that these are not robust tests to reveal either innocence or guilt, and characterizes cases where they may pardon a guilty firm (Type I error) or indict an innocent firm (Type II error). This paper also shows that a market share test can not be used to prove a dominant firm's intent for predatory pricing.     

A Test for a Functioning Market Economy: Seton'S Eigenprices of Turkey

We use Seton's eigenprices to see if some evidence can be found in support of the European Commission's official statement that the Turkish economy can be considered as a functioning market economy. Given an input–output flows matrix, there is a unique set of prices for outputs and production factors compatible with final demand, generating demand for factors. The findings based on Turkey's most recent I–O table and comparable I–O matrices for Romania and Poland (two EU members) in 2005 show that price distortions were on average five times larger in Turkey. Hence, based on price distortions alone, there was no solid evidence in support of the statement that Turkey had a functioning market economy.     

Optimal supervision intensity, collusion, and the organization of work

Abstract.  The intensity of supervision, defined as the proportion of supervisors to bottom-rank productive workers, differs widely across organizations and nations. Analysing three monitoring systems that differ in their supervision intensity, I show that the possibility of collective shirking arrangements can impose a system-dependent limit on the range of implementable performances. This brings about a tradeoff in the choice of the monitoring system: the system that economizes on incentive costs may implement an inferior range of performances. Applications of the model generate work-disutility-, ethics- and job-characteristics-based explanations for variations in the intensity of supervision.     

Factors Influencing Brand Launch in a Global Marketplace

The purpose of this study is to explore the factors that influence the launch of brands into new markets in a global environment. Although multiple streams of literature exist with respect to the entry of brands into new markets and the diffusion of new brands within and across markets, the process of launching products and brands globally over time has received relatively limited attention. To address this issue, this study incorporates multiple indicators of activities that can contribute to experiential learning relevant for launching brands in a global marketplace. Market uncertainty and experiential learning provide a conceptual foundation for the development of relevant hypotheses, which are tested in the context of the global automotive industry from 1981 to 2004. A discrete time event history analysis with time‐varying independent variables is employed to estimate the effects of the independent variables on the probability of a brand being launched in a specific market. The global brand launch observations are extracted from a proprietary dataset containing the global dispersion of automotive brands including 22 countries of origin and 42 countries of brand entry. The sample yields 50,572 spells, derived from 99 companies, 173 brands, and 700 market entries. The results of this study contribute to the literature in a variety of ways. Market attractiveness positively influences the propensity of a brand to be launched into a new market. This supports the idea that potential demand conditions are an important managerial consideration in product introduction decisions. The results reveal significant effects with respect to the role of psychic distance and experiential learning. Brands are reluctant to launch into countries that are culturally and economically less similar to the home market. Yet firms tend to place a lower degree of emphasis on factors of cultural distance when launching brands into larger markets, and global experience enables companies to overcome the uncertainties associated with launching brands into international markets that are economically distant. The results also suggest that companies are more likely to introduce additional brands in markets where they already have a presence. Overall, global dispersion and geographic scope, coupled with local market knowledge facilitate the launch of brands globally. From a managerial perspective, this study suggests companies should focus on acquiring both local and global experience to facilitate the launch of products and brands in the global marketplace.     

The Exchange Rate and the Trade Balances of Turkish Agriculture,Manufacturing and Mining

This paper investigates and compares the response to the exchange rate changes of trade balances of three Turkish sectors; agriculture, manufacturing and mining. The impact on trade balance of exchange rate changes is examined using the trade balance model employed in Bahmani-Oskooee [1985, Review of Economics and Statistics 67: 500]. Analysis is conducted based on the quarterly data from 1986: I to 1998: III. It is observed that in response to domestic currency depreciation trade balance of each of all three sectors first improves, then deteriorates and then improves again. Despite exhibiting similar pattern of reaction to the exchange rate change in the short run, long-run or overall response of trade balance differs across the sectors; while trade balances of both manufacturing and mining improve in the long run, agricultural trade balance worsens as a result of domestic-currency depreciation.     

Using strategic philanthropy to improve heritage tourist sites on the Gallipoli Peninsula,Turkey: community perceptions of changing quality of life and of the sponsoring organization

This paper examines the “Respect for History” project on Turkey's Gallipoli Peninsula sponsored by a Turkish oil company, OPET. The project sought to enhance and protect the cultural and historical experiences of tourists visiting Gallipoli, and to bring direct and indirect benefits to local communities through enhancing tourism-related business opportunities and improving community infrastructure. This research investigates the project's impact on residents’ perceived social and economic wellbeing, using a quality of life framework, and also ascertains residents’ views of the sponsoring firm. The context illustrates key differences between pure philanthropy and strategic philanthropy; the latter defined as doing good by purposefully achieving corporate and civic benefits. The role of strategic philanthropy as a sustainable tourism development tool, and its impact on tourism governance, are considered. Data were collected from 674 residents on the Turkish Gallipoli Peninsula in areas impacted by OPET's investment program. The results, using structural equation modelling (SEM), identify that respondents generally believe that both their economic and social quality of life have improved. This, in turn, has positively influenced respondents’ views of the sponsoring organization. The concept of strategic philanthropy appears valuable as a private sector, non-tourism, sustainable tourism development tool in some circumstances.
