Growth in overall life expectancy is straining the Social Security budget, and the gap in life expectancy between the rich and poor is widening. Motivated by these facts, this paper does four things. First, we develop a simple way to summarize the degree of progressivity in a Social Security system. Second, we show that growth in the life expectancy gap over the last few decades unwinds three-quarters of the progressivity of the Social Security system. Third, we develop simple reforms to Social Security that maintain the progressivity of the system and restore fiscal solvency. Fourth, we estimate the welfare effects of these potential reforms. 相似文献

Despite France's importance in the interwar world economy, the scale of the French banking crises of 1930–1 and their consequences have never been fully assessed quantitatively. The lack of banking regulation severely limited the availability of balance sheet data. Using a new dataset of individual balance sheets from more than 300 banks, this article shows that the crises were much more severe than previously thought, although they did not affect the main commercial banks. By reconstructing financial flows, this study shows that the fall in bank credit was mostly driven by a flight‐to‐safety by deposits, from banks to savings institutions and the central bank. The decrease in bank deposits due to bank runs was offset by an increase in deposits with savings institutions, with the central bank, and in cash hoarding, whereas the decrease in bank credit was not offset by an increase in loans from non‐bank financial institutions. In line with the gold standard mentality, cash deposited with savings institutions and the central bank was used to decrease marketable public debt and increase gold reserves, rather than pursuing countercyclical policies. Despite massive capital inflows and rising aggregate money supply, France suffered from a severe, persistent credit crunch. 相似文献

The paper examines the influence of mobile money usage on customer continuance intention (CCI). The study conveniently sampled 507 mobile money users to test the research model using PLS-SEM. Satisfaction, trust and active usage of mobile money were found to influence CCI. Active usage of mobile money was also confirmed as a mediator in the relationship between satisfaction and trust, on customer continuance. The study thus validated a theoretical model of customer continuance intention as it relates to mobile money usage. It has also provided a new perspective on managing customer churn in an emerging market. 相似文献

ABSTRACTStorage is one of the most important aspects of IT infrastructure for various enterprises. But, enterprises are interested in more than just data storage; they are interested in such things as more reliable data protection, higher performance and reduced resource consumption. Traditional enterprise-grade storage satisfies these requirements at high cost. It is because traditional enterprise-grade storage is usually designed and constructed by customised field-programmable gate array to achieve high-end functionality. However, in this ever-changing environment, enterprises request storage with more flexible deployment and at lower cost. Moreover, the rise of new application fields, such as social media, big data, video streaming service etc., makes operational tasks for administrators more complex. In this article, a new storage system called intelligent software-defined storage (iSDS), based on software-defined storage, is described. More specifically, this approach advocates using software to replace features provided by traditional customised chips. To alleviate the management burden, it also advocates applying machine learning to automatically configure storage to meet dynamic requirements of workloads running on storage. This article focuses on the analysis feature of iSDS cluster by detailing its architecture and design. 相似文献

Since December 2015, the Federal Reserve has operated a new “floor system” in which it brings about desired changes in its targeted federal funds rate by managing the interest rate it pays on bank reserves and other short‐term liabilities. The design of this new system reflects the tendency of Fed officials to view monetary policy as affecting the economy through Keynesian” interest rate channels. From this Keynesian perspective, policy actions that change the size of the balance sheet are seen as tools for influencing credit market conditions that operate in addition to and independently of the Fed's monetary policy stance. The alternative monetarist framework proposed by the author views monetary policy and its effects as operating through the interaction between money supply and demand. Use of this framework makes clear that, even under a floor system, monetary policy actions designed to affect the aggregate price level and the rate of inflation must be accompanied sooner or later by traditional open market operations that have implications for the size and composition of the Fed's balance sheet. Use of the monetarist framework also underscores the likelihood that the Fed, by paying interest on reserves, has unknowingly contributed to the restrictiveness of its own monetary policies since the financial crisis, a period during which inflation has run consistently below target. More generally, the monetarist framework downplays the importance of the zero lower interest rate bound and suggests that monetary policy could be conducted more effectively by adopting and adhering to a consistent, rule‐like manner during good times and bad. 相似文献

A compelling body of research has found that investments in knowledge from other firms and universities spill over to enhance the performance of entrepreneurial firms. This literature has shown that firm performance is positively related to investments in new knowledge by other firms and research universities. This paper addresses a gap in the literature by positing that public sector knowledge is also conducive to enhancing performance by knowledge intensive entrepreneurial (KIE) firms. Our findings suggest that the public sector provides a fertile source of knowledge for enhancing KIE firm performance.

Los autores ofrecen nuevos datos empíricos sobre la volatilidad en los ingresos y en el mercado de trabajo (incluyendo entradas y salidas del empleo) de los jóvenes en Europa durante la Gran Recesión. Los datos de EU‐SILC para el periodo 2004–2013 revelan grandes disparidades al respecto entre los países europeos. La Gran Recesión incrementó la volatilidad entre los jóvenes. Mediante un ejercicio de descomposición de la varianza se observa una mayor rotación laboral en el sur de Europa. Según un modelo de efectos fijos, un mayor nivel de prestaciones de desempleo y de protección del empleo se asocia con una reducción de la volatilidad. 相似文献

Emerging superstars on social media platforms reshape the media landscape. This research analyses social contagion as a stardom trigger of social media superstars (SMS). We argue that in addition to serving as a quality indicator, the number of observed consumers of SMS performances also indicates the suitability of discussing the SMS performances with others. We experimentally manipulated the number of previous views of a YouTube video and find that a high number of previous views significantly increases the perceived quality and the video’s discussion suitability even when holding all objective video characteristics constant. We discuss implications for aspiring SMS and (online) marketers. 相似文献
