The anticipated and concurring effects of the EMU: exchange rate volatility, institutions and growth

Reduced exchange rate volatility and higher and less heterogeneous quality of institutional rules and macroeconomic policies are two of the main (anticipated and concurring) effects expected from a currency union.In this paper, we measure the magnitude of these two effects for the Eurozone countries looking at real effective exchange rates (REER) and at different indicators of quality of institutional rules and macroeconomic policies (QIRMP). We find that the first effect is much stronger than the second when we compare relative changes for Eurozone countries and the rest of the world in the relevant period.We further evaluate the impact of both effects on economic growth on a larger sample of countries. Our findings show that both have significant impact on levels (more robust) and on rates of growth (weaker) of per capita GDP.     

我国经济发展水平与劳动力就业数量关系研究——兼论我国劳动力资源是否过剩

我国劳动力对经济发展而言，其生产率高于资本，因而经济发展对劳动力就业的促进作用逐渐减弱（经济增长的就业弹性逐渐变小）。据测算，我国2013年以前劳动力就业压力很大，2015年以后劳动力又会供不应求。所以，我国未来经济发展中，2014年前后应采用不同的产业结构调整策略来充分满足劳动力就业的要求。     

票据无权代理追认制度微探

票据行为是一种法律行为，自然也可以以代理方式为之。民法上有关代理制度的规则一般也都可以适用于票据代理行为。但由于民法与商事法的立法旨趣各有侧重，为促进票据流通、保障交易安全，票据代理不能照搬民法上关于代理制度的规定。票据的无权代理是票据代理中一个非常典型的问题，与民法上的无权代理区别很大，其中存在的问题很多。对于票据的无权代理中是否应当赋予本人以追认权，多数大陆法系国家的立法例与英美法系国家之立法例有所不同。

Past Returns and Investment Trust Discounts

Abstract:   The relationship between past net asset value returns and the current discount on investment trusts is investigated. The relationship is weaker for the component that is common to all trusts in the same sector, and is significantly stronger for more liquid trusts. The time lag before returns have their full impact on discounts is consistent with the requirements of distinguishing 'skill' from noise. Although discounts vary widely even within the same sector, the range of variation appears to be consistent with an arbitrage equilibrium, in which the profits of exploiting apparent pricing anomalies are just insufficient to invite arbitrage trades.     

Stock Market Valuation of Deferred Tax Assets: Evidence from Internet Firms

Abstract:   We use the provisions of SFAS No. 109 , Accounting for Income Taxes , to examine the extent to which stock prices of Internet firms were associated with expectations of future profitability before versus after the 'market correction' in early 2000. We find that the valuation of deferred tax assets of firms with business models reliant on the level of web site traffic was significantly greater after the market correction. In our view, this evidence is consistent with pre‐correction mispricing.

Technical Efficiency Estimates of Scottish Agriculture: A Note

Within the UK there has been a lack of studies of technical efficiency at the Scottish level. This note compares the results obtained using Scottish data with a recent study by Hadley [Journal of Agricultural Economics (2006) Vol. 57, pp. 81–100] for English and Welsh farms. Four major sectors are investigated, namely: (i) cereals, (ii) dairy, (iii) sheep and (iv) beef over the period 1989 to 2004. Some distinct differences in efficiencies, returns to scale and causes of efficiency are found.
