Measuring industrial upgrading: applying factor analysis in a global value chain framework

ABSTRACT

A key question for promoting international competition is how to improve the position of countries and industries in global value chains (GVCs). The first step is to properly measure industrial upgrading in GVCs. This is not a trivial issue because upgrading has not been defined unambiguously. Several authors have used different (and sometimes related) measures, all of which indicate certain aspects of upgrading. Rather than trying to find the single, ultimate measure of upgrading, we propose a different approach. We examine the multidimensionality of industrial upgrading, using eight indicators in factor analysis. Four of the eight indicators adopt the GVC perspective and include, for example, the growth of the share in value-added exports. We provide three quantitative dimensions of industrial upgrading: process upgrading, product upgrading, and skill upgrading. With these dimensions, we compare and analyze the upgrading of different countries and industries using the World Input–Output Database.     

Supply chain capabilities for facilitating the internationalisation of retailers – a multiple case study of three Swedish retail companies

ABSTRACT

Market-oriented aspects of retail internationalisation have received a lot of research attention since the 1990s. However, beyond these aspects lies also supply-chain oriented capabilities that are necessary for retailers to successfully internationalise into foreign sales markets. By using a perspective based on resource-based theories, this paper explores supply-chain oriented capabilities that facilitate retail internationalisation. The research is based on a multiple case study of three Swedish retailers. Through the perspective of research based theories, specifically capabilities, the empirical data is studied in a single-case as well as a cross-case analysis. Findings reveal three supply chain-oriented capability categories (leadership capability, integration capability and learning capability) of importance for retail internationalisation. Resources necessary for the capabilities are to be found internally at the retailer, but also externally at other firms. This research adds to the market-oriented knowledge on retail internationalisation by adding a supply-chain oriented perspective. Further, it provides an understanding of the early phases of retail internationalisation.     

The Monetary Transmission Mechanism, Non-residential Fixed Investment and Housing

We specify a vector autoregression (VAR) model for the U.S. for 1980–2008 to investigate the statistical causal relationships between private non-residential fixed investment, the effective Federal funds rate, personal consumption expenditures, nonfinancial corporate profits, and the nonfinancial corporate credit market debt to test the validity of macroeconomic relationships in a macro model. The VAR utilizes the Toda-Yamamote procedure to test for Granger causality. Our preliminary results show that the transmission mechanism does not work as expected; we find that fixed investment depends on the level of demand in the economy and profits but not on the interest rate. This casts doubt on the usual assumptions about how the monetary transmission mechanism is expected to work. The second part of the paper investigates the effects of the change in the monetary regime towards low and stable interest rates, a policy pursued by the U.S. Fed since the beginning of the 1990s. We find that the new monetary policy regime has the following effects: (1) our VAR model does not support the hypothesis that low interest rates lead to higher fixed nonresidential investment; (2) low interest rates led to a search for higher yields through increasing risk, and (3) they led to an increase in the demand for securitized assets, especially mortgage-backed securities, which eventually resulted in a housing bubble. The overall results therefore raise doubts about the effectiveness of low interest rates as a policy regime designed as a component of a counter-cyclical policy.     

On Conformity Testing and the Use of two Stage Procedures

Conformity testing is a systematic examination of the extent to which an entity conforms to specified requirements. Such testing is performed in industry as well as in regulatory agencies in a variety of fields. In this paper we discuss conformity testing under measurement or sampling uncertainty. Although the situation has many analogies to statistical testing of a hypothesis concerning the unknown value of the measurand there are no generally accepted rules for handling measurement uncertainty when testing for conformity. Usually the objective of a test for conformity is to provide assurance of conformity. We therefore suggest that an appropriate statistical test for conformity should be devised such that there is only a small probability of declaring conformity when in fact the entity does not conform. An operational way of formulating this principle is to require that whenever an entity has been declared to be conforming, it should not be possible to alter that declaration, even if the entity was investigated with better (more precise) measuring instruments, or measurement procedures. Some industries and agencies designate specification limits under consideration of the measurement uncertainty. This practice is not invariant under changes of measurement procedure. We therefore suggest that conformity testing should be based upon a comparison of a confidence interval for the value of the measurand with some limiting values that have been designated without regard to the measurement uncertainty. Such a procedure is in line with the recently established practice of reporting measurement uncertainty as “an interval of values that could reasonably be attributed to the measurand”. The price to be paid for a reliable assurance of conformity is a relatively large risk that the procedure will fail to establish conformity for entities that only marginally conform. We suggest a two‐stage procedure that may improve this situation and provide a better discriminatory ability. In an example we illustrate the determination of the power function of such a two‐stage procedure.     

In which financial markets do mutual fund theorems hold true?

The mutual fund theorem (MFT) is considered in a general semimartingale financial market S with a finite time horizon T, where agents maximize expected utility of terminal wealth. The main results are:

Panda and elephant – contesting animal icons in Thai tourism

In May 2009, during a period of rising political polarization in Thailand, a cub was unexpectedly born in Chiang Mai's Zoo to a pair of Chinese pandas. The authorities used the occasion to boost the crisis-ridden tourism to the northern Thai city, instigating an unprecedented national craze around the tiny cub, and promoting a massive pilgrimage of domestic visitors to the zoo. In a conspicuous act of protest against the prioritization of the foreign pandas, some elephant keepers in the Ayutthya kraal, painted their animals in panda colors, leading to an implicit contest between the two animal icons. In this case study, the wider theoretical and comparative implications of that contest are analyzed. Whereas previous studies of tourists engagement with captive wild animals paid scant attention to its wider social context, the article examines the cultural and economic background of the contest, and the manner in which it became implicated in the process of political polarization between the societal center and the periphery.
