When punishment fails: Research on sanctions, intentions and non-cooperation

People can become less cooperative when threatened with sanctions, and previous research suggests both “intentions” and incentives underlie this effect. We report data from an experiment aimed at determining the relative importance of intentions and incentives in producing non-cooperative behavior. Participants play a one-shot investment experiment in pairs. Investors send an amount to trustees, request a return on this investment and, in some treatments, can threaten sanctions to enforce their requests. Decisions by trustees facing threats imposed (or not) by investors are compared to decisions by trustees facing threats imposed (or not) by nature. When not threatened, trustees typically decide to return a positive amount less than the investor requested. When threatened this decision becomes least common. If the request is large relative to the sanction then most trustees return nothing. If the request is small, trustees typically return the requested amount. These results do not vary with investors' intentions.

Random walk and efficiency tests in the Asia-Pacific foreign exchange markets: Evidence from the post-Asian currency crisis data

This paper empirically tests the random walk and efficiency hypothesis for 12 Asia-Pacific foreign exchange markets. The hypothesis is tested using individual as well as panel unit root tests and two variance-ratio tests. The study covers the high (daily) and medium (weekly) frequency post-Asian crisis spot exchange rate data from January 1998 to July 2007. The inferential outcomes do not differ substantially between the unit root tests and the variance-ratio tests when using daily data but differ significantly when using weekly data. With the daily data, both types of unit root tests identify unit root components for all the series and two variance-ratio tests provide the evidence of martingale behavior for majority of the exchange rates tested. With the weekly data, panel unit root tests identify unit root component for the exchange rates and, the unit root tests on a single series basis identify unit root component for 10 foreign exchange markets. However, the variance-ratio tests reject the martingale null for the majority of the exchange rates when using weekly data.     

CONSUMER DIRECT FULFILLMENT PERFORMANCE IN INTERNET RETAILING: EMERGENCY TRANSSHIPMENTS AND DEMAND DISPERSION

The collaborative fulfillment of consumer orders by Internet retailers and wholesalers has proven important in the realization of sustainable levels of online profitability. Concentrating on consumer direct fulfillment (or drop shipping), an empirical simulation model evaluates avenues for improving logistical performance. The empirical simulation model centers on the online music CD retailing industry. It evaluates the effects of emergency transshipments and demand dispersion on inventory and product‐release performance, as well as on transportation costs, in consumer direct fulfillment operations. Results show that emergency transshipments improve inventory and product‐release performance in these operations. Furthermore, the inventory‐performance improvements are maximized when inventory facilities fulfill demand that is uniformly balanced across markets primarily assigned to each facility. Finally, gains in inventory and release performance obtained from emergency transshipments outweigh additional transportation costs incurred from a greater reliance on emergency transshipments for consumer direct fulfillment.     

Economists' perceptions versus managers' decisions: an experiment in transaction-cost analysis

Are the perceptions of professional economists on transactioncosts consistent with make-or-buy decisions made within firms?The answer may have important implications for transaction costresearch. Data on firms' outsourcing during the new productdevelopment process are taken from a large-scale survey of UK,German and Irish manufacturing plants, and we test the consistencyof these outsourcing decisions with the predictions derivedfrom the transaction cost perceptions of a panel of economists.Little consistency is evident between actual outsourcing patternsand the predictions of the (Williamsonian) transactions costmodel derived from the panel of economists. There is, however,evidence of a systematic pattern to the differences, suggestingthat a competence or resource-based approach may be relevantto understanding firm outsourcing, and that firms are adoptinga strategic approach to managing their external relationships.

Investigating the impact of demand amplification on freight transport

Despite freight transport operations being influenced by supply chain dynamics, there has been only a very limited investigation into the impact of demand amplification on this function, with almost no analytical research. This paper aims, through spreadsheet simulation of a generic production control system, to quantify the impact of demand amplification on transport performance. Performance measures evaluated include both transport cost and efficiency. The results in general find a negative relationship between transport performance and demand amplification. It is also found that the ratio of vehicle capacity to average demand affects these results.
