Estimating semiparametric panel data models by marginal integration

We propose an alternative method for estimating the nonlinear component in semiparametric panel data models. Our method is based on marginal integration that allows us to recover the nonlinear component from an additive regression structure that results from the first differencing transformation. We characterize the asymptotic behavior of our estimator. We also extend the methodology to treat panel data models with two-way effects. Monte Carlo simulations show that our estimator behaves well in finite samples in both random effects and fixed effects settings.     

北京市政策性农业保险巨灾风险防范机制探索

北京市政策性农业保险制度建立两年来已取得了初步成效,但如何化解面临的巨灾风险已成为促进北京市政策性农业保险制度持续健康发展面临的重要问题。无论是从制度要求、现实需求还是从政策需求来看,北京市建立政策性农业保险巨灾风险防范机制都是十分必要的。设立农业保险巨灾风险保障基金、建立农业再保险制度、发行农业保险巨灾风险证券等政策性农业保险巨灾风险的分散途径各有利弊。应构建多层次的农业保险巨灾风险防范机制。     

从经济区域比较看东北经济的振兴

东北经济的振兴恰逢中国的工业化进入重化工业发展的新阶段,东北经济的最大优势就是重化工业的物质基础和人力资本基础,重化工业化对东北经济的振兴是千载难逢,而且一旦失去就不会再来的重大机遇。从区域经济一体化的角度,审视东北经济的比较优势,并进行相应的产业整合,就成为东北经济振兴的必由之路。     

Managing Technological,Sociopolitical, and Institutional Change in the New Normal

A New Normal environment for business has emerged in the years after the 2008 financial crisis based on numerous changes in the world's economic, technological, demographic, and sociopolitical factors. This combination of changes has created a New Normal environment for firms with major implications for managers, strategists, and entrepreneurs alike. It has resulted in an environment with new challenges and opportunities that are considerably different from what firms had to contend with in the years previous. In this paper, we present the main changes that characterize the current New Normal business environment and highlight some key implications for strategy and management. Then, we present the nine articles in this special issue dealing with different dimensions of this new environment for firms. Subsequently, we outline some future research questions that could help to advance our knowledge of the New Normal environment and its implications for firms and management theories. In examining the New Normal, it is important to be reminded that the world is indeed round and even small actions on one side of the globe can have a major impact on organizations on the other side of the globe.     

Why firm size matters: investigating the drivers of innovation and economic performance in New Zealand using the Business Operations Survey

The performance of the New Zealand (NZ) economy is something of an enigma. Although ranked one (of 144 countries) for four important ‘growth fundamentals’ NZ is ‘middle of the pack’ when it comes to economic growth, productivity and process innovation. Using four iterations (2005, 2007, 2009 and 2011) of the Business Operations Survey, this research seeks to shed some new light on this conundrum by using a multivariate probit regression (mvprobit) approach applied to pooled samples in excess of 22,000 unit record observations of NZ firms. The results suggest that factors including firm size, high perceived quality, investment/research and development (R&D) capability, major technology change, application of formal IP protection and new export markets are systematically and positively related to innovation; while many external issues, such as those related to geography, market structure, business environment, have little influence. At the firm level, innovations in NZ are highly dependent on the firms’ internal ability to develop new technologies and market demand. The (very small) size of firms does matter in NZ, which lacks a major ‘home market’ or a major trade block on its doorstep, such that ultimately, government may need to be involved to maintain a viable scale for domestic R&D.     

Information on sellers and buyers characteristics: added value to explain price formation at primary fish markets in managed French scallop fisheries

The aim of this article is to explore, through a hedonic approach, the factors that might explain the price variability for the French-managed fishery of scallop at primary fish markets. In addition to factors classically identified in the current literature like intrinsic product characteristics or markets situation, the characteristics of operators are tested. The relationships of loyalty between sellers and buyers, and market assiduity are notably considered.     

An Evaluation of Inertia Models of Unemployment

Two approaches have been used to model unemployment. The first, conventional, approach involves linking the unemployment outcome to observed indices of productivity, structural factors and discrimination such as educational attainment, location and birthplace. The second approach, the inertia model, involves using a person's labour market history as a way of including in unemployment models information on the 'unobservables' that influence employability. This paper evaluates the performance of both models of unemployment. The results provide unambiguous support for the inertia model when modelling unemployment. The inertia model has higher explanatory power, higher within-sample prediction rate success and fewer out-of-sample forecasting errors than the conventional model. The estimates from the inertia model can be used to provide quite accurate predictions of the risk of becoming unemployed. This is important if individuals at high risk of becoming unemployed are to be targeted for labour market assistance.
