Collective Action and the Institutionalist Approach to Financial Regulation

Drawing on the institutionalist approach to a capitalist economy as a money economy, I regard financial regulation and supervision as a collective action problem. I argue that, given the basic characteristics of such an economy, a financial system may be considered as a public utility and financial stability as a public good. I then maintain that the provision of the latter could not rely on private market mechanisms, such as self-regulation and price-directed incentives. As capitalism develops through more financialized forms, new institutions and regulatory rules must be designed to reframe the market’s boundaries in order to consolidate systemic stability, which is a basic condition for continuous and sustainable economic relations in society. I then suggest a precautionary-principle-based macro-prudential approach to financial regulation in order to ensure a sustainable provision of finance and financial stability that is consistent with the characteristics of a money economy.     

Political Business Cycles and Partisan Politics: Evidence from a Developing Economy

This paper explores whether the evidence supports the Political Business Cycle (PBC) theory, Partisan Theory (PT), and Rational Partisan Theory (RPT) using stock market data from Turkey, a rapidly growing developing economy. The results indicate that the PBC hypothesis is not supported by the data. We find permanent partisan effects in the conditional variance but not in returns. The conditional volatility of the returns is higher during the periods in which a leftist party or a coalition government is in office. We also find that the stock market returns temporarily decreases (increases) at the beginning of a right‐wing (left‐wing) government, providing evidence in favor of RPT.     

Financial Liberalization as a Process of Flawed Institutional Change

I argue that the financial liberalization of the last decades, which resulted in a worldwide crisis, relied on an institutional change that ill-shaped actors’ behavior so as to let them enter into unsustainable speculative activities at the expense of macro-stability. To support such an assertion, I draw upon a specific Veblen-Minsky approach to a credit-money economy and its endogenous fragilities. I also maintain that, when financial markets are liberalized and private-interestsrelated self-regulation replaces public macro-prudential supervision, the financial system undergoes institutional deadlock and the ensuing confusion is transformed into a market gridlock. Markets then become unable to recover without public rescue operations of banks. The subsequent negative economic and social consequences are beyond the limits of any acceptable liberal ideology and scientific understanding. Therefore, systemic stability calls for a tighter macro-regulatory framework to remove the domination of speculative finance over economic decisions and activities.     

Stable schedule matching under revealed preference

Baiou and Balinski (Math. Oper. Res., 27 (2002) 485) studied schedule matching where one determines the partnerships that form and how much time they spend together, under the assumption that each agent has a ranking on all potential partners. Here we study schedule matching under more general preferences that extend the substitutable preferences in Roth (Econometrica 52 (1984) 47) by an extension of the revealed preference approach in Alkan (Econom. Theory 19 (2002) 737). We give a generalization of the Gale-Shapley algorithm and show that some familiar properties of ordinary stable matchings continue to hold. Our main result is that, when preferences satisfy an additional property called size monotonicity, stable matchings are a lattice under the joint preferences of all agents on each side and have other interesting structural properties.     

Income and consumption smoothing and welfare gains across Pacific Island Countries: The role of remittances and foreign aid

We examine the potential welfare gains and channels of income smoothing for Pacific Island Countries (PICs) and find that, under full risk sharing overall welfare gains across all PICs (particularly, Kiribati, Palau, and Papua New Guinea) are at desirable levels. However, for Australia, the potential welfare gain from risk sharing is almost similar to the gain it obtains if Australia attains full risk sharing with the rest of the OECD countries or with New Zealand alone. We also break down output using the framework of Sørensen and Yosha (1998) to quantify the extent and channels of risk sharing across PICs. For PICs, income-smoothing channels (net factor income and current transfers) play a significant role in buffering the output shock compared to the performance of those channels on smoothing the output shock for OECD countries. Domestic savings also smooth a fair portion of shocks to output, but the extent is much lower compared to that of OECD countries. Further, we analyze the effect of remittances and foreign aid on income smoothing for the PICs excluding Australia and New Zealand. Income smoothing via remittances is highly volatile and significant in recent years, while foreign aid seems to be a stronger and more stable channel for smoothing domestic output shocks for PICs.     

Statistical Arbitrage with Pairs Trading

We analyze statistical arbitrage with pairs trading assuming that the spread of two assets follows a mean‐reverting Ornstein–Uhlenbeck process around a long‐term equilibrium level. Within this framework, we prove the existence of statistical arbitrage and derive optimality conditions for trading the spread portfolio. In the existence of uncertainty in the long‐term mean and the volatility of the spread, statistical arbitrage is no longer guaranteed. However, the asymptotic probability of loss can be bounded as a function of the standard error of the model parameters. The proposed framework provides a new filtering technique for identifying best pairs in the market. Backtesting results are given for some of the pairs of stocks that are studied in the literature.     

The Revealed Preference Theory of Changing Tastes

We analyse preferences over finite decision problems in order to model decision-makers with „changing tastes”. We provide conditions on these preferences that identify the Strotz model of consistent planning. Building on an example given by Peleg and Yaari (1973) , we show that for problems with infinitely many choices, Strotz's representation of preferences may not be well defined. For that case, we propose a well-defined approximation which is empirically indistinguishable from the Strotz preference that is being approximated.     

Planning perceptions and planning results

The need for planning in business organizations operating in today's complex environment is widely accepted. Implied is an assumption that planning improves performance. However, the empirical evidence for such a claim is thin. Since planning is an integral part of strategy formulation, the facts to confirm or refute an assumed connection between planning and performance invite attention. Our research focuses on new data from 61 companies which test this linkage and, in addition, reviews the conclusions of prior empirical studies.     

The impact of group-oriented values on choice of conflict management styles and outcomes: an empirical study in Turkey

Globalization has led to increased attention to cultural diversity in workforces and its influences on organizational practice. This study examines group-oriented values and their impact on choice of conflict management styles as well as on conflict resolution outcomes in Turkey. Using a sample of 315 managerial personnel from various public and private organizations, this study shows that norms of subordination of personal needs to group interests and beliefs about the effects of personal pursuit on group productivity are the most important predictors of choice of conflict management styles in Turkey. In addition, dominating and obliging styles are associated with individual profits in actual conflict resolution process and integrating style is the primary determinant of satisfaction and relationship building in conflict management. Managerial implications are then discussed on diversity and conflict management training for effective international human resources management.     

Determinants of Fresh and Frozen Fruit and Vegetable Expenditures in Turkish Households: A Bivariate Tobit Model Approach

In this study, we have identified the effects of socio-demographic and economic factors of household heads and households on monthly expenditures of fresh and frozen fruit and vegetable in Turkey using the bivariate Tobit model. The results show that both the probability and monthly spending levels of household fruit and vegetable consumption increase with increasing in age of household heads, educational levels of household heads, married household heads, household income, and the number of adults in a family, while male-headed households, working household heads, the households that receive in-kind help from the government or private sector, and the use of internet at home decrease both the likelihood and spending levels of fruit and vegetable consumption in Turkey. The results in the study may contribute to the stakeholders to identify and implement effective marketing strategies and also develop more effective policies for the government to improve nutritional levels for certain dwellings for which the government include them in the certain state-initiated benefit program.
