Cross-border integration is a multifaceted as well as contextually contingent process. While various conceptualisations have been developed, the theoretical foundations of the concept appear insufficient in order to grasp the very significance of such a process of cross-border regionalism. In order to help make sense of the diversity of configurations observed, this article seeks to deconstruct the concept according to the role played by the border as a resource and to develop a theoretical framework based on two contrasted models of cross-border integration. The underlying hypothesis is that cross-border integration does not derive from the mere opening of national borders that it supposedly helps at the same time to remove, but stems from the strategic behaviour of actors who actively mobilise borders as resources. The first model, called ‘geo-economic’, is mainly based on the mobilisation of the border as a differential benefit and aims to generate value out of asymmetric cross-border interactions. In doing so, this process of functional integration is likely to increase cross-border socio-economic disparities and leads to cooperation oriented towards instrumental purposes such as increasing the economic utility of the border or regulating negative externalities. The second model, called ‘territorial project’, emphasises the border resources that involve a convergence of both sides of a border, either through a process of hybridisation/innovation or via the territorial and symbolic recognition borders entail. In this process of place-making that transcends the border, mutual understanding and trust between the actors is seen to be key and the willingness to cooperate essential. Conceived as ideal-types, the two models of cross-border integration are contrasted and to some extent contradictory. They are however not mutually exclusive and different kinds of combinations are examined based on concrete examples. 相似文献

How to share money creation among the members of the European Monetary Union? To address this issue, we construct a two‐country New Open‐economy Macroeconomics model of an asymmetric monetary union with an incomplete financial market and home bias in consumption. We consider two sharing rules consistent with the current regulations of the European System of Central Banks. First, each participating National Central Bank supplies half of the European Central Bank determined money creation in the monetary union. Secondly, each National Central Bank adapts the national increase in money demand, under the constraint that the total money creation in the union does not exceed the level determined by the ECB for the whole union. We show that the current sharing rule, which ignores countries’ heterogeneity, is superior in terms of welfare. The key role of the current account is emphasized. It proves an efficient decentralized mechanism for allocation of money. 相似文献

Let be an -valued special semimartingale on a probability space with canonical decomposition . Denote by the space of all random variables , where is a predictable -integrable process such that the stochastic integral is in the space of semimartingales. We investigate under which conditions on the semimartingale the space is closed in , a question which arises naturally in the applications to financial mathematics. Our main results give necessary and/or sufficient
conditions for the closedness of in . Most of these conditions deal with BMO-martingales and reverse H?lder inequalities which are equivalent to weighted norm inequalities. By means of these last inequalities,
we also extend previous results on the F?llmer-Schweizer decomposition. 相似文献

In this paper we study both the level of Value-at-Risk (VaR) disclosure and the accuracy of the disclosed VaR figures for a sample of US and international commercial banks. To measure the level of VaR disclosures, we develop a VaR Disclosure Index that captures many different facets of market risk disclosure. Using panel data over the period 1996–2005, we find an overall upward trend in the quantity of information released to the public. We also find that Historical Simulation is by far the most popular VaR method. We assess the accuracy of VaR figures by studying the number of VaR exceedances and whether actual daily VaRs contain information about the volatility of subsequent trading revenues. Unlike the level of VaR disclosure, the quality of VaR disclosure shows no sign of improvement over time. We find that VaR computed using Historical Simulation contains very little information about future volatility. 相似文献

We examine daily short selling of Nasdaq stocks to explore whether speculative short selling causes a significant portion of the weekend effect in returns. We identify a weekend effect in speculative short selling whereby it constitutes a larger percentage of trading volume on Mondays versus Fridays. We find an opposite effect in dealer short selling, consistent with market makers adding liquidity and stability. Our main finding is that speculative short selling does not explain an economically meaningful portion of the weekend effect in returns, even among the firms most that are most actively shorted. This finding contradicts some prior studies. 相似文献

Without convergence of macroeconomic parameters representative of the nature of adjustment mechanisms, even a common shock
to members of a monetary union can lead to different macroeconomic consequences across the union and, eventually, to the need
for more or less co-ordinated specific policies. In this paper, we test for the presence of convergence of the Okun’s Law
coefficient (OLC) among several alternative groupings of European economies. The empirical strategy adopted is based on the
evaluation of the time path of rolling regression estimates of the OLC for European countries. We then use a testing procedure
suggested by Evans [Evans P (1996) J Econ Dynam Control 20:1027–1049] to investigate the convergence, or non-convergence,
of the OLC in several groups of European countries by examining how the cross-country variance of the OLC evolves over time
in these groups. A hypothesis of medium-term convergence of the OLC is rejected for most of the European country groups examined.

In this paper we assess the relative contribution of working conditions to wage determination with an emphasis on differences along the earnings distribution. A survey of British employees in 2001 rich in questions regarding the job post enables us to separate the contribution of working conditions, job attributes and individual characteristics to the process of wage determination. Standard wage equations reveal that covariates such as having “repetitive job” and using generic skills such as “literacy” or “customer handling skills” are associated with significant premiums and penalties. Quantile regressions confirm the presence of penalties to poor working conditions, such as “working to tight deadlines”, that are significant in the middle section of the earnings distribution and robust to the inclusion of a wide range of controls for person, firm and other job characteristics. Counterfactual decompositions at quantiles show that, despite the apparent penalty, there are pecuniary compensations to poor working conditions around the first quartile and the median of the earnings distribution. 相似文献

A recent JAMS article reported the following finding: the longer the time between the launch of two adjacent generations in
the same product category, the lower the initial rate of adoption of the later generation but the higher its subsequent rate
of growth. This note shows that these results could be a method artifact, since they vanish once one controls for differences
in the length of the data series used to compute the initial and subsequent rates of growth. So, for the time being, it is
premature to accept these intergeneration effects as genuine.

This paper studies a unique buyback method allowing firms toreacquire their own shares on a separate trading line whereonly the firm is allowed to buy shares. This share repurchasemethod is called the Second Trading Line and has been extensivelyused by Swiss companies since 1997. This type of repurchaseis unique for two reasons. First, unlike open market programs,the repurchasing company does not trade anonymously. Second,all transactions made by the repurchasing firm are publiclyavailable in real time to every market participant. This isa case of instantaneous disclosure which contrasts sharply withother markets characterized by delayed or no disclosure. Wedocument that the daily repurchase decision is statisticallyassociated with short-term price changes and the release offirm-specific news. We also find that repurchases on the secondtrading line have a beneficial impact on the liquidity of repurchasingfirms. Exchanges and regulators may consider the second tradingline an attractive share reacquisition mechanism because ofits transparency and positive liquidity effects. 相似文献

The recent important transformations of the banking sector, especially through numerous mergers and acquisitions, both in Europe and in the USA, have raised serious concerns for the financing of small businesses (SBS). Indeed, SBS are known to be heavily dependent of this financing channel but to be rather opaque. It has long been thought that banks classically solved this problem by developing long term customer relationships. But will the new large banks, born from the current restructuring process, be able to continue to play this role? If not, what strategy should SBS develop to compose their bank pool in order to avoid, as much as possible, credit rationing? These questions are at the heart of our analysis. We show that there is no unique rule: all depends on the degree of SBS opacity and the kind of bank the SBS are working with. 相似文献
