Earnings inequality and the informal economy

We analyse the extent and evolution of informality and inequality in the Serbian labour market between 2002 and 2007, using data from the Living Standard Measurement Surveys. Two surprising results emerge. First, the level of informal employment has risen significantly over the period, despite strong economic growth and the introduction of a range of market‐oriented reforms. Secondly, the level of inequality in earnings seems to have remained more or less constant over the period, in contrast to the experience of other countries at a similar stage of transition. We show that informal employees earn significantly less than those in the formal sector, controlling for a range of other variables, and informality plays an increasingly important role in explaining earnings inequality.     

Transitions to low carbon transport futures: strategic conversations from London and Delhi

Climate change is a global problem and across the world there are major difficulties being experienced in reducing carbon dioxide (CO₂) emissions. The transport sector in particular is finding it difficult to reduce CO₂ emissions. This paper reports on two studies carried out by the authors in London (UK) and Delhi (India). It considers the common objectives for transport CO₂ reduction, but the very different contexts and baselines, potentials for change, and some possible synergies.Different packages of measures are selected and scenarios developed for each context which are consistent with contraction and convergence objectives. CO₂ reduction potentials are modelled and quantified by package and scenario. London is considering deep reductions on current transport CO₂ emission levels; Delhi is seeking to break the huge projected rise in transport CO₂ emissions.The scale of policy intervention required to achieve these goals is huge and there is certainly little public discussion of the magnitude of the changes required. The paper argues for a ‘strategic conversation’ at the city level, using scenario analysis, to discuss the priorities for intervention in delivering low carbon transport futures. A greater focus is required in developing participatory approaches to decision making, alongside network investments, urban planning, low emission vehicles and wider initiatives. Aspirations towards equitable target emissions may assist in setting sufficiently demanding targets. Only then is a wider awareness and ownership of potential carbon efficient transport futures likely to take place.     

重大保险风险测试及其对再保险定价的影响

2010年我国保险行业实施《企业会计准则解释第2号》后,在保费收入的会计确认上发生了重大变化,要求保险公司对签订的再保险保单进行重大保险风险测试。重大保险风险测试对再保险保单的影响重大,本文主要阐述重大保险风险测试问题的提出以及主要测试方法,并从实务角度出发,分析我国的重大保险风险测试规定对临时再保险、非比例合约再保险和比例合约再保险等再保险保单定价的影响。     

Cournot Competition and Hit-and-Run Entry and Exit in a Teaching Experiment

Instructors can use a computerized experiment to introduce students to imperfect competition in courses on introductory economics, industrial organization, game theory, and strategy and management. In addition to introducing students to strategic thinking in general, the experiment serves to demonstrate that profits of a firm fall as the number of competitors is increased in a market and that firms enter profitable markets. The authors have used the experiment in undergraduate classes on strategy and management as well as in master of business administration courses with great success.

FLAC2D数值模拟技术在路堤堆载工程中的应用

对路堤堆载工程中路堤与地基结合部(即坡角)容易发生塌陷、滑坡等不稳定现象的原因进行了认真的剖析,并利用FLAC2D数值分析技术对路堤堆载工程中路堤发生的应力、应变及位移进行了详细分析,同时绘制出了路堤堆载前后路堤的竖向应力云图、水平位移云图、最大不平衡力变化曲线图、表层沉降曲线图。通过数值模拟我们发现了引起路堤滑坡的症结所在,提出了安全防范措施,确保了安全生产。     

Notes on some present day Questions regarding Mortality

Abstract

In the absence of any definite development of actuarial science in Great Britain which would be a suitable subject for this paper I considered that the most useful course would be to discuss some of the problems which are at present exercising my own mind, and no doubt the minds of many of my colleagues. Probably, many of these questions are akin to others which arise in other countries, so that their discussion at a meeting such as this may prove of mutual interest, while even if they are peculiar to ourselves, a disclosure of our doubts and difficulties will indicate the directions in which future developments may be expected. I must, however, emphasize that any views expressed are purely personal, and do not in any way pretend to represent a consensus of British actuarial opinion. Throughout this paper only Ordinary (as opposed to Industrial) business in considered.
