Developing a financial conditions index for a post-transition country: the case of Croatia

The interconnection between financial and business cycles and the importance of surveillance over financial markets emphasise the need for the development of indicators that could trace financial conditions in a country. In this paper, we focus on developing a financial conditions index for a post-transition country – Croatia. Since financial conditions indices for post-transition markets differ from those for developed markets due to differences in the development of their financial systems and the availability of data, we show that financial conditions indices constructed for post-transition markets need to be tailored to the specifics of such markets.     

Intertemporal production and intertemporal substitution in output supply and input demand

This article presents an intertemporal model of production with multiple inputs to investigate substitution opportunities facing firms over time. The firm’s intertemporal profit maximization problem is characterized with the familiar cost function, and various intertemporal substitution elasticities are delineated for output supply and input demand. The absence of intertemporal substitution in production can imply production smoothing, and allowance for intertemporal substitution in labour demand reinforces the prediction of the real business cycle model. For aggregate US manufacturing, we find substantial substitution in output supply and labour demand over time due to intertemporal changes in output price and wage rates.     

Regional and gender differentials in the persistence of unemployment in Europe

The persistence of unemployment increased during the recent great recession in many European countries, although with diversified impacts. We therefore analyse such impacts in four European countries – Italy, Spain, France and the UK – which represent different institutional frameworks and may reflect the so-called continental European and Anglo-Saxon frameworks. We analyse the determinants of unemployment persistence using individual-level data from the European Union Statistics on Income and Living Conditions (EU-SILC) panel for the period 2007–2013. These data enable us to take into account initial conditions and state dependence in addition to individual and household characteristics. We focus on gender and regional effects, which have a strong impact on the persistence in the state of unemployment. We find that gender gap is significant in Italy and the UK, implying that male workers show a higher probability of remaining unemployed. In Italy, such a pattern is due to the worsening of male workers’ conditions during the crisis, whereas in the UK, male workers show higher unemployment rates than women. Regional effects are significant in all countries analysed and underline a relevant structural factor that should be addressed on policy grounds in Europe. Such effects are greater in Spain and Italy.

资本深化带来了经济危机吗

本文对美、日两国的资本深化过程和经济危机过程的考察结果表明两者之间有紧密的相关关系。按照索洛的稳态增长条件理论,资本深化并不必然带来经济危机。但资本—劳动比不断增长的现实最终会使资本深化远离稳态水平,越来越大的资产价格泡沫和过高的人均资本量只有通过经济危机的爆发来消除和降低。研究结果表明,扩大社会就业和加大民生工程支出等是防止人均资本量过高即资本深化引致经济危机爆发的有效措施。     

状语“更”与情态补语共现的类型及条件

状语＂更＂与情态补语共现,状语＂更＂的语义指向上存在差异,有的指向情态补语,有的指向述语。状语＂更＂与情态补语共现受隔指凸现焦点、语法匹配因素、功能匹配因素、语义匹配因素四种条件的限制。     

梯形明渠正常水深和临界水深的迭代计算法

图解法和试算法是计算正常水深和临界水深通常采用的方法,但计算精度欠佳且计算步骤繁杂。文章提出了一个新的迭代方程用于上述2种水深的计算,并用代数方法严格地证明了该方程具有收敛性。     

广西地下水功能区划分初探

Characterization of bidding behavior in multi-unit auctions

This paper considers a very general class of single or multi-unit auctions of indivisible objects. The model allows for interdependent values, multidiminensional types and any attitude towards risk. Assuming only optimal behavior, we prove that each bid is chosen in order to equalize the marginal benefit to the marginal cost of bidding. This generalizes many existing results in the literature. We use this characterization to obtain sufficient conditions for truthful bidding, monotonic best reply strategies and identification results for multi-unit auctions.
