Regímenes de producción y relaciones laborales en el sector chino del automóvil

Las huelgas en el sector del automóvil acaecidas en China en 2010 suscitaron reformas sustanciales de las relaciones laborales en la provincia de Guangdong. A partir de una investigación empírica exhaustiva en empresas líderes de ensamblaje y en sus suministradoras, el autor construye una tipología de los regímenes de producción para analizar los cambios actuales de las relaciones laborales. Este marco ayuda a entender y a conceptualizar la diversidad creciente de regímenes en la industria china automotriz y la segmentación de la fuerza de trabajo a lo largo de la cadena de suministro. Se concluye con un análisis de las perspectivas de reforma ulterior.     

INTEREST RATE CORRIDOR,LIQUIDITY MANAGEMENT,AND THE OVERNIGHT SPREAD

We analyze the determinants of the overnight spread (the spread between the Borsa Istanbul overnight repo interest rate and the average funding rate of the Central Bank of the Republic of Turkey [CBRT]) using data from both the conventional and the new monetary policy episodes. We empirically document that the overnight spread has recently been influenced by various factors that are directly or closely related to the liquidity policy of the CBRT. (JEL E43, E52, C24)     

What preconceptions and attitudes about engineering are prevalent amongst upper secondary school pupils? An international study

In the Netherlands, as well as in many other countries, there is an increasing interest in implementing education about engineering as a part of general education at the upper secondary school level. In order to know what pupils at that level think about engineering, a study has been done to investigate their attitude towards and their concept of engineering. This study was done not only in the Netherlands but also in 39 other countries. In the preparation of the study, pupils were asked to draw concept maps of what they thought engineering was about. In the quantitative main part of the study, pupils were asked to respond to 33 Likert-type attitude items and 32 concept-items of the same type. A factor analysis was done in order to reveal the dimensions in the pupils’ attitude and concept. In contrast to studies carried out amongst students in lower secondary school levels, a fairly clear concept about engineering was found. The gender differences relating to engineering, found in lower secondary education, were not found in upper secondary education. The prevalent attitude of students towards engineering indicated a fairly positive image of engineering.     

Reversal of Monday returns

This paper elaborates an interesting aspect of the Monday anomaly: Monday returns are relatively more likely to reverse over the subsequent days. We document that, although the Monday low-return anomaly disappeared, the subsequent reversal of Monday returns remains robust to date. The reversals, measured over a five-day horizon, are pervasive across international stock markets, reasonably stable over time, significant following both positive and negative Monday returns, and not confined to extreme Monday returns. Trading strategies designed to exploit these reversals earn economic profits. We examine potential explanations for the reversal of Monday returns using trading flows data of investor types from Korea. All predictions of the Foster and Viswanathan [J. Finance, 1993, 48, 187–211] model are confirmed: volatility is higher, trading volume is lower, market depth is lower and price impact costs are higher on Mondays. The model implies lower price quality on Mondays, but does not specifically predict reversal of Monday returns. We show that the trading intensity of international/institutional investors is lower on Mondays. This appears to make the market relatively more susceptible to individual investors’ trading, which is negatively correlated with international/institutional investors. Thus, Monday returns are relatively more likely to reverse during the subsequent days of the week when institutional investors trade more aggressively.     

What Accounts for the Changes in U.S. Fiscal Policy Transmission?

Using vector autoregressions on U.S. time series for 1957–79 and 1983–2004, we find government spending shocks to have stronger effects on output, consumption, and wages in the earlier period. We try to account for this observation within a DSGE model featuring price rigidities and limited asset market participation. Specifically, we estimate the structural parameters of the model for both periods by matching impulse responses. Model‐based counterfactual experiments suggest that most of the changes in fiscal policy transmission are accounted for by increased asset market participation and the more active monetary policy of the Volcker–Greenspan period.     

Income distribution and exchange in a dynamic search model

This paper studies the link between income distribution and trade mechanisms in a dynamic search model with two-sided asymmetric information. Buyers and sellers have imperfect information about the income levels of the other group. Furthermore, asymmetry of information about incomes is the source of price dispersion. In such a frictional environment, we capture the effects of a change in inter- and intra-class income distribution on the trade mechanism, which is represented by the expected trade volume and the flux of buyers and sellers in the market.     

Tax Progression under Collective Wage Bargaining and Individual Effort Determination

We study the impact of tax policy on wage negotiations, workers’ effort, employment, output, and welfare under imperfectly observable effort. A higher degree of tax progression always leads to wage moderation, but the well‐established result from the wage bargaining literature that a revenue‐neutral increase in the degree of tax progression is good for employment does not carry over to the case with wage negotiations and imperfectly observable effort. Introducing tax progression increases employment and output, but we cannot rule out that the negative effort effect of increasing tax progression will lead employment to fall when tax progression is already high.     

ECONOMIC ADJUSTMENT IN HEAVILY INDEBTED DEVELOPING COUNTRIES

The threat to the international financial system resulting from the developing-country debt problem has diminished since the initial 1982 crisis, despite halting adjustment and impaired creditworthiness in heavily indebted developing countries. The threat to the financial system has eased as commercial banks have reduced sharply the share of their assets and capital exposed to the troubled debtor countries. The countries themselves, however, are no better off. A sizable balance-of-payments adjustment has occurred in the heavily indebted developing countries, but that adjustment was concentrated–at least in quantitative terms–during the years immediately following the onset of the crisis and might have been more efficient had it been executed more gradually. Despite the adjustment that has occurred, the creditworthiness of the heavily indebted countries–as evaluated by conventional indices–has not improved. And, for reasons that this article explores, economic growth per capita has not resumed either.     

Knowledge Types in Technology

Starting with the distinction of natural science, engineering science ("technology") and engineering practice ("technics"), the paper will stress the difference between technological and technical knowledge. The first part will discuss the relationship between science and technology, arguing that technology is a genuine type of knowledge rather than "applied science". In technics, however, even technological laws, as transformations of scientific laws, cover a certain part of knowledge only. The greater part of technical knowledge includes technical know-how, functional rules, structural rules, and socio-technological understanding, which is just developing in our times. The classification of knowledge types will be used for determining which kind of knowledge may seem appropriate to general technological education.
