The effect of free trade agreements revisited: Does residual trade cost bias matter?

This paper revisits a prominent gravity model‐based empirical literature on the effects of free trade agreements by accounting for a potential bias caused by unobservable trade costs that operate through general equilibrium constraints. It embeds state‐of‐the‐art panel estimation techniques in a recently proposed two‐step remedy that features a constrained ANOVA‐type estimation. Using a dataset on manufacturing trade flows in eight sectors in 40 countries and a rest‐of‐the‐world aggregate for the period 1990–2002, it finds evidence of significant residual trade cost bias. The direction and magnitude of bias vary across sectors, with the standard one‐step approach used in the literature overestimating or underestimating the partial effect of free trade agreements by up to 110 percent. Overall, coefficients on trade costs variables are jointly significantly different between the standard method and the two‐step method. The biases in partial effect estimates translate into biases in general equilibrium effects.     

Management of sustainable fashion retail based on reuse– A struggle with multiple logics

ABSTRACT

In scholarly conversations, reuse is one of the common suggested strategies to render fashion retail sustainable. Previous research has stressed the complexity of fashion reuse and the importance of a well-organized system. The complexity stems from processes that involve many actors as well as products hard to evaluate. Consequently, it is challenging to organize reuse-based fashion retail, and studies are needed to further develop knowledge regarding how to manage such systems. Hence, the purpose of this paper is to highlight the complexity in the management of such an initiative, by identifying and explaining obstacles as well as implications. With institutional logics as a framework, three local logics (shopping mall, reuse, and work integration) are used to analyze the management of a reuse-based mall. Despite the mall’s success in getting sufficient donations and creating publicity, it has struggled to establish itself as viable reuse-based fashion retail. The findings illustrate the complexity created by the interplay of different logics and how the complexity influences both the daily and strategic management of the mall. Further, the outcome of this interplay depends largely on which rationality is enacted by involved actors. The study also extends literature on institutional logics, showing that differences in individual actors’ attention, knowledge, skills, coordination, and material conditions influence how logics are enacted and managed. We suggest that there are inherent managerial contradictions in the sustainable practices in fashion retail. Thus, in scholarly conversations, it is important to discuss what different divergent sustainability dimensions imply when seeking solutions for sustainable retail. In practice, there is a need to acknowledge and balance the presence of multiple logics, making it crucial to have competence in all logics. Also, managers of reuse-based fashion retail must consciously and continuously scrutinize their own strategies and actions to avoid an imbalance between the logics.     

Impact of frequency of alignment of physical and information system inventories on out of stocks: A simulation study

Inaccuracy in the information system inventory as compared to the physical inventory may lead to out of stocks. Inaccuracy may occur for many reasons, a principal one being random losses such as theft. One way to reduce this inaccuracy is to adjust the inventory information in the systems at some regular frequency. Such alignments are quite expensive in practice. Thus how often to align the two inventories is the focus of this research. A simulation model is employed to investigate the effect of such loss defined by the stock loss parameter (λ) and the frequent alignment of physical and information system inventories on the stockout (S_out) and average inventory (I). A term to be called the effective value of stock loss parameter is introduced to signify the effect of frequency of alignment (f) on S_out. The results derived in this study provide a powerful tool in the hands of an inventory manager. It has been noted that, so far as stockout is concerned, by selecting a moderate value of alignment frequency (f), the effective value of stock loss parameter (λ_e) can be reduced to∼ λ/f. The accuracy of S_out and I values across a number of runs in the simulation studies, sensitivity of S_out and I on various parameters and the nature of stochastic demand distribution, and application of these results with or without deployment of RFID to reduce the loss due to stockout are also discussed. The results, verified under various scenarios, indicate that there is a significant reduction in stockout loss when the alignment is done monthly vs. annually, but it does not add much value beyond a monthly check.     

THE COMPLEX RESPONSE OF MONETARY POLICY TO THE EXCHANGE RATE

We estimate a flexible non‐linear monetary policy rule for the United Kingdom to examine the response of policymakers to the real exchange rate. We have three main findings. First, policymakers respond to real exchange rate misalignment rather than to the real exchange rate itself. Second, policymakers ignore small deviations of the exchange rate; they only respond to real exchange under‐valuations of more than 4% and over‐valuations of more than 5%. Third, the response of policymakers to inflation is smaller when the exchange rate is over‐valued and larger when it is under‐valued. None of these responses is allowed for in the widely used linear Taylor‐type rules, suggesting that monetary policy is better analysed using a more sophisticated model, such as the one suggested in this paper.
