MEASURING LIMITS OF ARBITRAGE IN FIXED‐INCOME MARKETS

An emerging literature relies on an index of limits of arbitrage in fixed‐income markets. We analyze the benefits of an index that is model‐free, robust, and intuitive. This new index strengthens the evidence that limits of arbitrage proxy for risks priced in the cross‐section of returns. Trading simulations show that the new index improves identification of limits of arbitrage because it bypasses a noisy estimation step. Relative value indices in the United States, United Kingdom, Japan, Germany, Italy, France, Switzerland, and Canada exhibit strong commonality and high correlations with local volatility and funding conditions. The indices are updated regularly and available publicly.     

When trade unions turn to litigation: ‘getting all the ducks in a row’

Driven by their members' demands and the need to adopt more combative legal strategies in order to oppose the deterioration of working and employment conditions, British trade unions have developed in‐house legal expertise and supported many individual and multiple claims. This article investigates the variation in unions' legal practices and examines their organisational responses to law and the role of compliance professionals in the regulation of employment litigation. It provides a nuanced account of the influence of legal rationality on the framing of union strategies and shows that, under certain conditions, trade unions are able to build multi‐pronged tactics by using litigation as a complement to other forms of action.     

The role of the entrepreneurial encounter in the emergence of opportunities: Vallée’s Dallas Buyers Club

ABSTRACT

This paper aims to explore the conceptual potential of the Deleuzian notion of the encounter in order to better understand the genealogy of opportunities. We adopt a processual perspective of opportunities. In order to translate this notion to the domain of entrepreneurship, we analysed and interpreted Jean-Marc Vallée’s Dallas Buyers Club. This film follows the creation of the first club in the United States that illegally allowed HIV-positive people to supply themselves with foreign antiretroviral drugs from Mexico or Japan. The article highlights encounters in this process that disturb the entrepreneur’s belief systems and allow him or her to be open to potential opportunity. It finally explores how the encounter may improve our understanding of the political becoming of opportunities within the entrepreneurial process.     

Identifying fiscal policy (in)effectiveness from the differential counter‐cyclicality of government spending in the interwar period

Differences across decades in the counter‐cyclical stance of fiscal policy can identify whether the growth in government spending affects output growth and so speeds recovery from a recession. We study government‐spending reaction functions from the 1920s and 1930s for twenty countries. There are two main findings. First, surprisingly, government spending was less counter‐cyclical in the 1930s than in the 1920s. Second, the growth of government spending did not have a significant effect on output growth, so that there is little evidence that this feature of fiscal policy played a stabilizing role in the interwar period.     

互联互通——竞争力的关键 加强亚欧航空互联互通,促进双方经济社会关系

<正>航空互联互通——竞争力的关键航空互联互通在当今经济全球化中起着至关重要的作用。对亚欧而言,要想从各自的发展潜力中获利,在双方的经济中心区域建立频繁可靠、方便快捷的航空联系则变得至关重要。保持良好的航空互联互通,是保障亚欧各城市和各区域处于强有力竞争力位置的基本要素。不必讶异,无论是在地方、国家甚至国际的政策讨论中,互联互通都是一个越来越重要的话题。例如,伦敦某机场在讨论新增跑道时,连通新兴市     

In Search of the Transmission Mechanism of Fiscal Policy in the Euro Area

This paper applies the DSGE‐VAR methodology to assess the size of fiscal multipliers in the data and the relative contributions of two transmission mechanisms of government spending shocks, namely hand‐to‐mouth consumers and Edgeworth complementarity. Econometric experiments show that a DSGE model with Edgeworth complementarity is a better representation of the transmission mechanism of fiscal policy as it yields dynamic responses close to those obtained with the flexible DSGE‐VAR model (i.e. an impact output multiplier larger than one and a crowding‐in of private consumption). The estimated share of hand‐to‐mouth consumers is too small to replicate the positive response of private consumption. Copyright © 2016 John Wiley & Sons, Ltd.     

Two-stage non Gaussian QML estimation of GARCH models and testing the efficiency of the Gaussian QMLE

In generalized autoregressive conditional heteroskedastic (GARCH) models, the standard identifiability assumption that the variance of the iid process is equal to 1 can be replaced by an alternative moment assumption. We show that, for estimating the original specification based on the standard identifiability assumption, efficiency gains can be expected from using a quasi-maximum likelihood (QML) estimator based on a non Gaussian density and a reparameterization based on an alternative identifiability assumption. A test allowing to determine whether a reparameterization is needed, that is, whether the more efficient QMLE is obtained with a non Gaussian density, is proposed.     

Who produces for whom in the world economy?

Abstract For two decades, the share of trade in inputs, also called vertical trade, has been dramatically increasing. In reallocating trade flows to their original input‐producing industries and countries, this paper suggests a new measure of international trade: ‘value‐added trade’ and makes it possible to answer the question ‘who produces for whom?’ In 2004, 27% of international trade was vertical trade. The industrial and geographic patterns of value‐added trade are very different from those of standard trade. Value‐added trade is relatively less important in regional trade but the difference is not more important for Asia than for America.
