The day of the week effect on stock market volatility

This study tests the presence of the day of the week effect on stock market volatility by using the S&P 500 market index during the period of January 1973 and October 1997. The findings shown that the day of the week effect is present in both volatility and return equations. While the highest and lowest returns are observed on Wednesday and Monday, the highest and the lowest volatility are observed on Friday and Wednesday, respectively. Further investigation of sub-periods reinforces our findings that the volatility pattern across the days of the week is statistically different.(JEL G10, G12, C22)     

Denomination composition of trade and trade balance: evidence from Turkey

The currency denominations of a country's exports and imports are not necessarily the same. If this is the case, then a change in the exchange rate parity among major currencies will affect the trade balance. The empirical evidence provided from Turkey – where exports are mostly denominated in Euros and imports are mostly denominated in USD – suggests that an appreciation of the Euro against the USD would increase the output in the long-run, appreciate the local currency and improve the trade balance for the 1985:01 2003:07 period.     

Institutional impact and quote behavior implications of the options penny pilot project

In this study, we expand the analysis of the impact of the options penny pilot project (PPP) using a sample that covers the first three phases of the project, a control group of options that were not part of the project, and options market specific control variables. We show that proportional national best bid offer spreads decrease significantly for the pilot securities, with the control sample demonstrating a general increase in relative spreads. Regression analysis indicates that a decrease in relative spreads can be explained by the switch to penny quoting. We find that the average quote size significantly declines and most pilot securities experience significant increases in quote traffic during the pilot period. For equity options in the pilot group we do not find a pattern of change in the average trading volume that can be attributed to the PPP. The average trading volume shows a general increase for the ETF options in the pilot group during the pilot period. Based on the findings derived from a sample of opening and closing “large” trades, we do not find conclusive evidence that trading in penny increments has a negative impact on the volume of institutional trading activity on the options exchanges during the first few months of Phase I. Our results for relative spreads, average quote size, quote traffic and trading volume are robust to Phases I–III of the PPP.     

Turkish monetary policy and components of aggregate demand: a VAR analysis with sign restrictions model

This article estimates the effects of monetary policy on components of aggregate demand using quarterly data on Turkish economy from 1987–2008 by means of structural Vector Autoregression (VAR) methodology. This study adopts Uhlig's (2005) sign restrictions on the impulse responses of main macroeconomic variables to identify monetary shock. This study finds that expansionary monetary policy stimulates output through consumption and investment in the short-run. However, expansionary monetary policy is ineffective in the long-run.     

Openness and the Effectiveness of Monetary Policy: A Cross-country Analysis

Abstract

This paper evaluates the relationship between a country's openness to trade and the effectiveness of monetary policy in changing output growth and inflation in 29 different countries. Using quarterly data from the 1957–2003 period, empirical estimates based on individual country specifications show that the direction, significance and nature of the relationship between openness and the effectiveness of monetary policy on output growth as well as inflation vary considerably across countries.     

Patterns of alignment in alliance structure and innovation

Alliances are becoming an increasingly common strategy for product development despite the intrinsic tension between alliance logic and innovation logic. This paper investigates the development of alliance structures during the exploration phase of the innovation process. Based on a study of five service development alliances in the telecom industry, three patterns are identified by which the alliance structure and the innovation are brought into alignment. Such alignment seems to be a necessary condition for the transition into commercialization. The patterns identified are: (1) Learning about the innovation may trigger changes in the alliance structure; (2) Learning about the innovation may suggest changes in the alliance structure that are impossible to implement, however, thus triggering changes in the innovation; (3) Planning the future alliance structure may suggest changes in the innovation. Based on these patterns, some conclusions and implications are identified, for both theory and practice.     

Bilateral versus Multilateral Free Trade Agreements: A Welfare Analysis

Why is a proliferation of bilateral free trade agreements (FTAs) between certain types of countries observed instead of progress in attaining global free trade through a multilateral FTA? This paper answers this question by exploring the enforceability of different types of FTAs through comparing minimum discount factors that are necessary to sustain them in an infinitely repeated game framework. The authors search for the globally welfare maximizing trade agreements that are sustainable under different conditions. The results depict that transportation costs, differences in country sizes and comparative advantages are all obstacles for having a multilateral FTA. Accordingly, international development policies conducted for the removal of such obstacles should be the main goal toward achieving a multilateral FTA, which is shown to be the first‐best solution to the maximization problem of global welfare.     

Manifest anxiety,general self-efficacy and locus of control as determinants of personal and general risk perception

The hypothesis that risk perception is associated with differences in personality was proposed. Three personality variables were used, Rotter's Internal vs External Locus of Control Scale, Schwarzer's General Self-efficacy Scale and Taylor's Manifest Anxiety Scale. A scale asking for personal and general risk perception measured perceived risk. It was proposed that individuals low in anxiety, having an internal locus of control and high in self-efficacy should perceive general risks and personal risks higher than individuals high in anxiety and low in self-efficacy and having external locus of control should do. Fifty-nine business students responded to these three scales. The hypothesis was supported by the results and suggested that the personality measures and particularly anxiety were significantly associated to both personal and general risk perceptions.     

Monetary policy and U.S. long-term interest rates: How close are the linkages?

The effect of monetary policy on long-term interest rates has been a question of interest in recent years. A number of papers, relying on single-equation estimation techniques, have presented evidence that long-term interest rates exhibit sizable and significant responses to unanticipated changes in the Federal Reserve's target federal funds rate. This paper examines these findings in light of conflicting findings from VAR studies, which indicate negligible effects of innovations in the federal funds rate on long-term rates. To address the issue we use a single-equation approach where unanticipated changes in the federal funds rate are measured as residuals from policy reaction functions. We also estimate VAR specifications, which incorporate information about the timing of changes in the Federal Reserve's target federal funds rate. Our single-equation estimates provide evidence of strong responses of long rates to unanticipated changes in the federal funds rate both for the Greenspan period and for a longer period back to the mid-1960s. It seems likely that estimated VARs for the post-1987 years are less successful in isolating monetary policy surprises than was the case for earlier years.
