校园大气环境污染现状

在区域污染源调查基础上,对校园大气环境质量进行了现状监测与评价,结果表明,校园大气环境已受到较重污染,SO_2,NO_x,TSP一次浓度在各监测点处不超标或最大超标0.25倍;SO_2,TSP日均浓度在各监测点处均有超标现象,最大分别超标0.71～1.43倍、0.92～1.37倍;并对污染原因进行了分析。     

Sustainable and Excessive Current Account Deficits

Both the Mexican crisis of 1994–95 and the Asian financial crisis of 1997–98 have been preceded by large current account deficits run by the affected economies. External deficits are often assumed to play an important role in the propagation of financial crises in emerging markets. Policymakers are faced with a new challenge: that of resisting or accepting the large current account deficits that may result from heavy private capital inflows. This paper aims at providing some guidance:First, the Lawson Doctrine – according to which current account deficits that result from a shift in private-sector behaviour should not be a public policy concern – has been discredited by recent currency crises in Latin America and Asia. Second, define the size of current account deficits that should be sustainable in the long run. Third, the intertemporal approach to the current account does not provide a reliable benchmark to define when deficits become excessive. Fourth, large external deficits should be resisted if unsustainable currency appreciation, excessive risk-taking in the banking system and a sharp private spending boom are seen to coincide.

Capital Inflows to Hungary in 1995–96 and the Accompanying Policy Responses

In order to analyze the composition and effects of, and the policy responses to, capital inflows to Hungary during 1995–96, we present an analytical framework that emphasizes the distinction between net capital flows to the private and public sectors (the latter includes the government and the central bank). This distinction is essential in Hungary's case, because figures for overall net inflows conceal the fact that huge net capital inflows to the private sector were accompanied by large repayments of foreign public debt, covered by significant privatization revenues. We present indicators of the domestic monetary impact of net capital inflows in order to analyze the magnitude, costs, and effects of sterilization. We note that extensive sterilization and the use of privatization revenues for public debt repayment largely explain why capital inflows to Hungary did not have significant effects on the real economy or on domestic monetary aggregates in the period reviewed.     

Demographic changes, saving, and current account: An analysis based on a panel VAR model

This paper empirically investigates the macroeconomic effects of demographic changes, focusing on saving rates and current account balances. The econometric investigation based on the panel VAR model shows substantial demographic effects on national saving rates and current account balances in the major advanced (G-7) countries. An increase in the dependency rate significantly lowers saving rates, especially public saving rates. Further, a higher dependency rate significantly worsens current account balances.     

What's next in key account management research? Building the bridge between the academic literature and the practitioners' priorities

This research contrasts the academic literature on key account management (KAM) with the topics in this subject that are most critical to practitioners. Sixty four academic articles published in 17 journals, and ninety practitioners' articles appearing in the Velocity Magazine — published by the Strategic Account Management Association — were content analyzed and classified under ten ‘topic’ categories. Similarities and differences in the results for academics and practitioners are discussed. In addition, two specific topics were identified as being extremely important to managers but still under-researched by academics: the role of senior management in KAM, and the importance of internal alignment in determining KAM success.
