Delaying the Normal and Early Retirement Ages in Spain: Behavioural and Welfare Consequences for Employed and Unemployed Workers

In this paper, we explore the links between pension reform, early retirement, and the use of unemployment as an alternative pathway to retirement. We use a dynamic rational expectations model to analyze the search and retirement behaviour of employed and unemployed workers aged 50 or over. The model is calibrated to reproduce the main reemployment and retirement patterns observed between 2002 and 2008 in Spain. It is subsequently used to analyze the effects of the 2011 pension reform in Spain, characterized by 2-year delays in both the early and the normal retirement ages. We find that this reform generates large increases in labour supply and sizable cuts in pension costs, but these are achieved at the expense of very large welfare losses, especially among unemployed workers. As an alternative, we propose leaving the early retirement age unchanged, but penalizing the minimum pension (reducing its generosity in parallel to the cuts imposed on individual pension benefits, and making it more actuarially fair with age). This alternative reform strikes a better balance between individual welfare and labour supply stimulus.     

评估“正确”的风险

正董事会会议中经常会传来这样的声音:我们所要冒的险值得吗?尤其是在战略对话中,这个问题看似简单、常见,但答案却不简单无论管理层和董事会是否意识到,风险隐藏于任何组织的战略里,潜伏在你所做的一切决定中:拓展新市场;引进新产品;购买生产线;筹建新厂房;投资未知的研发活动等。一个公司的战略方向和执行战略方向的能力是这次冒险之旅能否成功的关键。因此,风险评估应该是战略制定过程中不可或缺的一部分。     

Latin America after the global crisis: the role of export-led and tradable-led growth regimes

Is the ongoing economic slowdown in industrialized countries likely to impact Latin American growth negatively in the medium- to long-run? This paper considers various transmission channels that work through trade in goods and services, and finds econometric evidence suggesting that shrinking global imbalances may create problems for Latin America. Specifically, using panel data analysis, we find that the trade balance as a proportion of GDP is positively associated with Latin American economic growth over the period 1953–2009. We then develop a simple dynamic model to help explain our main finding through investment and saving behaviour.     

Corporate cash holdings and political connections

We examine the relation between corporate liquidity and political connections measured via lobbying expenditures. This is an interesting question as many of the motives for holding cash should be diminished by political connections. Results indicate a significant and inverse relation between cash levels and lobby expenses and that the marginal value of cash decreases with lobbying. Taken together, these findings suggest firms react optimally to the reduced benefits of cash linked to political connections and that the market recognizes the weakened benefits of cash. Overall, our research shows another way political connections can shape corporate policy.     

BE/ME and E/P work better than ME/BE or P/E in regressions

Researchers often form ratios of variables to measure firm characteristics, but which ratios create the most powerful tests? For example, if we use ratios of book value of equity (BE) and market value of equity (ME), or earnings (E) and price (P), does it matter which variable appears in the denominator? Any variable in the denominator, when close to zero, creates outliers and is less likely to produce effective tests. Our tests, using data from 1972 to 2008, indicate the choice between reciprocals often produces significantly different outcomes. While ME/BE is a more commonly used control variable than BE/ME or LN(BE/ME), we find the latter two produce better results, even if the data are trimmed to mitigate the outlier problem. Similarly, using E/P generally produces better results than P/E, and while ratios with book value of assets (BA) in the numerator work better than those with it in the denominator, the difference is less pronounced than when BE or E is part of the ratio. While the focus of our empirical findings is on growth measures, the principal applies anytime a ratio has a denominator that is frequently near zero.     

Information technology innovation in India: The top 100 IT firms

Patents serve as an indicator of the innovation capability of countries, industries, or firms. Many Indian firms are in a transition to move from labor intensive segments to areas with higher value added which has been reflected in this research. The purpose of this study is to analyze patents issued during the period of 1997–2009 from the European Patent Office database and the United States Patent and Trademark Office database from the top one hundred Indian information technology firms. This study represents a novel empirical look at information technology industry innovations in India. A comprehensive set of statistical patent analyses are presented to provide practitioners with valuable knowledge to assist in business strategic planning.     

ASYMPTOTICS OF IMPLIED VOLATILITY IN LOCAL VOLATILITY MODELS

Using an expansion of the transition density function of a one‐dimensional time inhomogeneous diffusion, we obtain the first‐ and second‐order terms in the short time asymptotics of European call option prices. The method described can be generalized to any order. We then use these option prices approximations to calculate the first‐ and second‐order deviation of the implied volatility from its leading value and obtain approximations which we numerically demonstrate to be highly accurate.
