Design of randomized experiments to measure social interaction effects

We consider randomized experiments with two levels of randomization for measuring social interaction effects. We examine how the randomization should be carried out to estimate the coefficients of interest most precisely.     

The effects of time pressure and information load on decision quality

This study attempts to identify conditions under which consumer information overload occurs. A theory which states that information overload will occur when the time-related task demands exceed the capacity of the system is suggested and tested. An experiment is reported in which an inverted U-shaped function relating decision quality to information load occurred when time pressure was present, but did not when it was absent.     

Macro foundations of micro-economics

This paper attempts to circumvent the nonsense of the representative agent which arises in macroeconomics. It recognises that macro data are relevant to agents' decisions, and so excess demands should contain macro variables as arguments. The macro variables I consider are the price index, unemployment and GNP. This paper should be regarded as a tentative beginning to make macroeconomic theory literate.

Bid-Rigging in Auctions for Korean Public-Works Contracts and Potential Damage

This research is an empirical study to find solid statistical evidence of collusion inauction for construction contracts and to gauge the possible effects of bid-rigging onauction prices in Korea. Using limited information contained in sketch bid data, weshow that local construction firms enjoy statistically significant incumbency premiumsin their incumbent sites. Thus, it is inferred that contractors engage in complementarybidding, in which all bidders, except one, submit high bids so as to lose. The statisticalevidence of the incumbency effect is also confirmed in long-running civil engineeringconstruction contracts, which are carried out over several years. Utilizing the transitionfrom a cooperative to non-cooperative regime, we also estimate the potential damage ofstructural bid rigging in public-works contracts by year, contractor and construction type. The estimated overcharge ratio based on a forecasting approach is 15.5% of the total expenditures from January 1995 to June 1998. We also present potential damage estimates by the firm. The estimated overcharge by contractor offers a guideline for the proper allocation of the total overcharges to construction contractors in case contractors are charged with bid-rigging and found guilty.     

Accounting research: An analysis of theories explored in doctoral dissertations and their applicability to Systems Theory

This study examined theories used in accounting doctoral dissertations and found that dissertations in this discipline test theories drawn from economics, finance, psychology, and sociology, with 53% from economics and finance and 27% from psychology. Further, a primary conclusion of this paper is that doctoral research in accounting explores subsets of organizational activity consistent with the premises of Systems Theory.     

Assurance of learning: The impact of business core course reviews on students’ scores on the comprehensive business exam for both internal and external comparative purposes

This study is the first to explore how business core course review sessions impact standardized test results. A statistically significant improvement in students’ overall scores of 16.5% was identified when core course reviews were conducted between Comprehensive Business Exam pre- and posttest dates. As a result, institutional results moved from slightly above average to the upper 15th percentile among institutions employing this exam. Additionally, scores for the economics, finance, management, and marketing core-course subject matter areas significantly improved. A review did not significantly improve scores in the accounting concept area. Implications for assurance of learning analysis are presented.     

How do Scientists Contribute to the Performance of Innovative Start‐ups? An Imprinting Perspective on Open Innovation

Our study illustrates how scientists contribute to the performance of innovative start‐ups through an analysis of 211 Italian start‐ups with and without scientist founders. Building upon imprinting theory, we hypothesize and find that scientists provide an advantage to innovative start‐ups to the extent that they stimulate open innovation (i.e., search breadth and depth). However, for this to effectively occur, the involvement of multiple scientist founders is needed, so that their career imprints internalized in the lab are successfully transferred to the start‐up. Moreover, if the start‐up embraces business practices (i.e., strategic planning) or departs from scientific logics (i.e., pursuing non‐commercial goals), scientists’ contribution is further increased. Therefore, our study illustrates how the scientist career imprint can provide an advantage to innovative start‐ups with multiple scientists, but also how it can act as a rigidity if the start‐up does not pursue strategic planning or emphasizes non‐commercial goals.     

Housing market volatility connectedness among G7 countries

This study investigates international linkages among housing markets in the G7 countries, using the connectedness methodology developed in Diebold and Yilmaz (2012, 2015). We find that volatility connectedness varies over the business cycle, with a surge during the global financial crisis. We also show that the United States and Italy were major net transmitters of housing market volatility shocks to other countries during the global financial crisis and the European debt crisis, respectively.     

Trade Liberalisation and the Wage Skill Premium in Korean Manufacturing Plants: Do Plants’ R&D and Investment Matter?

This paper examines the effects of output and input tariff reductions on within‐plant wage skill premium in Korean manufacturing plants. We find evidence that output tariff reduction interacts differently with plants’ R&D and investment behaviours, respectively, to affect wage skill premium. More specifically, output tariff reduction increases wage skill premium mostly in R&D‐performing plants while reducing it mostly in plants making positive facility investments. While there is weak evidence that input tariff reduction increases wage skill premium, no such interactive effects are found. One story behind our results is that, although both R&D and facility investments may respond to changes in profit opportunities due to output tariff reductions, R&D raises the relative demand for the skilled workers while facility investment, an activity of increasing production capacity, raises the relative demand for the unskilled workers.
