This article investigates how fundamental labour rights specified in international framework agreements are implemented and monitored in subcontracting chains. It shows how labour's capacity for workplace‐based monitoring is influenced by factors such as ownership structures, the societal context, and, most importantly, the institutions and dynamics of local labour control.  相似文献

Abstract Why do borders still matter for economic activity? The reunification of Germany in 1990 provides a unique natural experiment for examining the effect of political borders on trade. With the fall of the Berlin Wall and the rapid formation of a political and economic union, strong and strictly enforced administrative barriers to trade between East Germany and West Germany were eliminated completely within a very short period of time. Remarkable persistence in intra‐German trade patterns along the former East‐West border suggests that border effects are neither statistical artefacts nor driven by administrative barriers to trade, but arise from economic fundamentals.  相似文献

This study analyzes the value created by so-called "toolkits for user innovation and design," a new method of integrating customers into new product development and design. Toolkits allow customers to create their own product, which in turn is produced by the manufacturer. In the present study, questions asked were (1) if customers actually make use of the solution space offered by toolkits, and, if so, (2) how much value the self-design actually creates. In this study, a relatively simple, design-focused toolkit was used for a set of four experiments with a total of 717 participants, 267 of whom actually created their own watches. The heterogeneity of the resulting design solutions was calculated using the entropy concept, and willingness to pay (WTP) was measured by the contingent valuation method and Vickrey auctions. Entropy coefficients showed that self-designed watches vary quite widely. On the other hand, significant patterns still are visible despite this high level of entropy, meaning that customer preferences are highly heterogeneous and diverse in style but not completely random. It also was found that consumers are willing to pay a considerable price premium. Their WTP for a self-designed watch exceeds the WTP for standard watches by far, even for the best-selling standard watches of the same technical quality. On average, a 100% value increment was found for watches designed by users with the help of the toolkit. Taken together, these findings suggest that the toolkit's ability to allow customers to customize products to suit their individual preferences creates value for them in a business-to-consumer (B2C) setting even when only a simple toolkit is employed. Alternative explanations, implications, and necessary future research are discussed.  相似文献

The short-run effects of fungicide application on economic risk and the effects of risk on fungicide use in Swiss wheat production are empirically explored. A quadratic production function model is developed. With the help of the moment-based approach, marginal contributions of fungicides (representing controlled inputs) and of rain (representing uncontrolled inputs) to the variances of yield and revenue are analyzed. It is not possible to show risk-reducing effects of fungicides on yield or revenue. At low rain quantities during the vegetation period fungicides have a statistically significant risk-increasing effect on revenue. Increasing risk leads Swiss wheat growers to use more fungicide. This increase is statistically significant at higher levels of revenue. For example, when risk is doubled fungicide inputs are raised by 44% at the highest revenue quartile.  相似文献

We propose a methodology for forecasting the systemic impact of financial institutions in interconnected systems. Utilizing a five-year sample including the 2008/9 financial crisis, we demonstrate how the approach can be used for the timely systemic risk monitoring of large European banks and insurance companies. We predict firms’ systemic relevance as the marginal impact of individual downside risks on systemic distress. So-called systemic risk betas account for a company’s position within the network of financial interdependencies, in addition to its balance sheet characteristics and its exposure to general market conditions. Relying only on publicly available daily market data, we determine time-varying systemic risk networks, and forecast the systemic relevance on a quarterly basis. Our empirical findings reveal time-varying risk channels and firms’ specific roles as risk transmitters and/or risk recipients.  相似文献

The total cash issuance of a central bank consists of domestic transaction and hoarding balances as well as foreign demand. The different shares are not known exactly. The introduction of the new Europa series of banknotes in the euro area offers the opportunity to calculate transaction balances with the help of a biometric method. Our results indicate that transaction balances are very low.  相似文献

This paper addresses the debate about the usefulness of high‐frequency (HF) data in large‐scale portfolio allocation. We construct global minimum variance portfolios based on the constituents of the S&P 500. HF‐based covariance matrix predictions are obtained by applying a blocked realized kernel estimator, different smoothing windows, various regularization methods and two forecasting models. We show that HF‐based predictions yield a significantly lower portfolio volatility than methods employing daily returns. Particularly during the 2008 financial crisis, these performance gains hold over longer horizons than previous studies have shown, translating into substantial utility gains for an investor with pronounced risk aversion.

In this roundtable, an adviser to several central banks and founding member of the Group of 30 discusses regulatory reform and corporate risk management strategies with senior executives from three of the world's largest insurance companies. Much of the discussion attempts to explain why insurance and reinsurance companies have proven less vulnerable to the crisis than commercial and investment banks. Part of the explanation has to do with their financial conservatism, which is attributed to a habitual tendency to decision‐making that gives heavy weight to long‐term probabilities and risks. But along with this “actuarial” cast of mind is a growing willingness to accept and make use of risk‐based capital requirements—a decision‐making framework that is, in some respects, in conflict with the accounting and regulatory capital conventions that still prevail in the industry. In particular, “Solvency II”—the risk‐based capital guidelines that are set for adoption in 2012 by insurers in the European Union—is held up as a possible model for global use.  相似文献
