Does trade integration alter monetary policy transmission?

This paper explores the role of trade integration—or openness—for monetary policy transmission in a medium-scale new Keynesian model. Allowing for strategic complementarities in price setting, we highlight a new dimension of the exchange rate channel by which monetary policy directly impacts domestic inflation: a monetary contraction which appreciates the exchange rate lowers the local currency price of imported goods; this, in turn, induces domestic producers to lower their prices too. We pin down key parameters of the model by matching impulse responses obtained from a vector autoregression on time series for the US relative to the euro area. Our estimation procedure yields plausible parameter values and suggests a strong role for strategic complementarities. Counterfactual simulations show that openness alters monetary transmission significantly. While the contractionary effect of a monetary policy shock on inflation and output tends to increase in openness, we find that monetary policy's control over inflation increases, as the output decline which is necessary to bring about a given reduction of inflation is smaller in more open economies.     

缅甸瑞丽江一级水电站至达贡山镍矿输电线路拼抢工期的若干措施

文章阐述了缅甸瑞丽江一级水电站至达贡山镍矿220 kV送电线路工程拼抢工期的若干措施,尤其指出大件材料在雨季前运输到现场材料站、将组织不力的施工分包商断然换下、对雨季材料中运的路面进行处理等措施的施行,能使工程满足合同对工期的要求。实践表明,这些非常措施对赢得工程工期是行之有效的。

Gender discrimination,inflation, and the business cycle

Empirical evidence suggests that women are discriminated against in the labor market. We analyze the effects of taste-based and statistical gender discrimination on business cycle and inflation dynamics by including unpaid household production, two-agent households, and discriminatory firm behavior in a tractable New Keynesian model. After a negative demand shock, we find that the economic downturn is more severe in comparison to a non-discriminatory environment, as the shock implies an increase in the inefficient utilization of female and male productivity. Furthermore, the working time allocation between women and men becomes more inefficient. Moreover, we show that discrimination implies a lower transmission of expansionary monetary policy shocks on inflation. Overall, taste-based discrimination leads to larger macroeconomic distortions, while statistical discrimination implies higher intra-household inefficiencies.
