Abstract. The high-frequency analysis of foreign exchange dynamics is helpful in order to better identify the impact of central bank interventions. Evidence robustly shows that interventions do indeed move the exchange rate level in the desired direction. Interventions increase volatility in the short run as they are regarded as information; but they can reduce volatility overall. Ways of transmission may reach beyond the signalling channel and also include the portfolio balance and a damping channel. Finally, interventions are more successful if they obey certain conditions, such as being coordinated among central banks and going with the market and fundamentals. 相似文献

The United Nations Development Program has published its Human Development Index values for most countries of the world for
the past five years. It claims the index provides information that goes beyond the widely-used GDP data and is relevant for
policy-making. Critical examination shows that the index does not yet live up to this claim. 相似文献

We analyze the cost savings potential with regard to administration and management costs by merging Commercial Employment Accident Insurance Funds (Berufsgenossenschaften) in Germany. We use data from the German Federation of institutions for statutory accident insurance and prevention (HVBG) for 1999 to 2004. Large Berufsgenossenschaften (BGs) have lower administration and management costs per insured person. However, costs per insured person are negatively correlated with insured risk of the BGs which in turn is an important source of administration and management costs.Results of a multivariate regression analysis help to identify cost drivers and the existence of economies of scale. Notifiable accidents, occupational diseases and risk explain administration and management costs. All estimation results are highly significant and allow to conclude that remarkable economies of scale are likely to be present in the organization of the BGs. Our results are robust to alternative specifications. Also, risk turns out to be an important cost driver with regard to management costs.A hypothetical policy reform is considered that reduces the number of BGs from formerly 35 to 18. We come up with an estimate of expected cost savings (without cutting benefits) of 83 million euros, about 10 % of the current management costs of the BGs under consideration. 相似文献

This paper analyses the macroeconomic effects of the European Central Bank’s asset purchase programme in its initial version and subsequent modifications under the lens of a dynamic macroeconomic model, which includes assets of different types and maturity, and explicitly introduces asset purchases of long-term bonds (held by euro area and non-euro area residents) by the central bank. With imperfect substitutability between asset classes, portfolio rebalancing in the context of quantitative easing (QE) affects bond yields, stock prices, the exchange rate and the private sector’s saving decision. QE as announced in January 2015 generates 0.4% effective euro depreciation and raises real GDP in the euro area by 0.2% and prices by 0.3% by 2017 in the model. The subsequent extensions of the QE programme (extension in time and increase in volume) more than double the medium-term output and inflation effects according to the simulations. 相似文献

The note analyses interactions between nominal wage stickiness and costly employment adjustment under rule-based and optimal monetary policy. Policy regimes affect and optimal policy lowers the welfare cost of rigidities. No quantitatively important second-best interaction between both rigidities is found. 相似文献

This paper examines the relative information shares of the Bund, i.e. the 10-year Euro bond future contract on German sovereign debt, versus two futures with shorter maturity. We find that the Bund is most important but does not dominate price discovery. The other contracts also have relevant - and at many days even higher - information shares. In examining determinants of information shares, we add order flow measures to market state variables and macroeconomic news. More order flow in a contract consistently increases this contract’s information share. 相似文献

The paper investigates the link between monetary policy and structural reforms in open economies. We test three hypotheses:
(a) the Calmfors hypothesis that the degree of reforms is higher in the case of autonomous policy and lower in the case of
commitment, (b) the TINA hypothesis which implies a positive impact of a monetary policy rule on the extent of reforms, and
(c) a third factors hypothesis. In our empirical analysis on panel data of 23 OECD countries from 1980–2000 we find little
evidence for the Calmfors hypothesis, but evidence in favor of the TINA argument for labor market and regulatory reform.

ABSTRACTSeveral recent publications have argued that the use of heuristics by financial investors can distort global capital flows, but scholars have paid little attention to the scope conditions that determine when heuristics become influential (and when they don’t). Building on work in economic sociology and behavioural finance we suggest that the degree to which investment heuristics can bias aggregate capital flows depends on the levels of uncertainty and self-referentiality that structure the environments under which investment decisions are being made. Applying these insights to the two principal global markets for corporate investment, we argue that the institutional structure of markets for short-term portfolio equity investments (PEI) is far more conducive to trigger the mimetic adoption of a specific heuristic than in markets for long-term foreign direct investments (FDI). To test this hypothesis, we leverage the high level of arbitrariness of the selection of Brazil, Russia, India and China into the BRIC acronym and empirically examine the impact of its remarkable rise to prominence among communities of financial investors in the mid-2000s on global capital flows to emerging economies. In line with the theoretical argument, we find robust evidence of a strong BRIC-bias in markets for PEI but not FDI. 相似文献

The study considers the simultaneous estimation of share equations using cost and distance functions. Simultaneous rather than single system estimation utilizes full as opposed to limited information. Econometric results exploit the nonstationary nature of the data and that variables are cointegrated. Under cointegration all variables are endogenous and so it is not necessary to undertake the somewhat ad hoc exercise of choosing instruments to achieve parameter consistency. Johansen's maximum likelihood estimator is applied to data from Central Canada and Western Canada (1935–2006). Symmetry and homogeneity restrictions are not rejected for either region. Monotonicity held for all data points and concavity held at 92% of the data points. Long‐run constant returns and Hicks neutral technological change are rejected for both regions. Morishima elasticity estimates coming from the cost function in Western Canada indicate highly elastic long‐run substitution between the land/fertilizer input pair and mildly elastic long‐run substitution between land and both machinery and labor. In contrast, substitution for land and other inputs is inelastic for the land/machinery pair and the land/labor pair, with only the land/fertilizer pair being mildly elastic. The results indicate the limiting nature of land as a fundamental constraint on long‐term agricultural production is a real possibility in Central Canada because other inputs are inelastic, or at best only mildly elastic, substitutes for land. In Western Canada, fertilizer is the only factor that is highly substitutable for land and, therefore, could mitigate the limiting nature of land in that region. However, given that fertilizer applications are often considered to be environmentally unfriendly, the long‐run substitution of fertilizer for land as a fundamental mitigating factor to land scarcity in Western Canada is at a cost to the environment. 相似文献
