Danish flexicurity: preconditions and future prospects

This article argues that Danish flexicurity is preconditioned by craft unionism that has historically been predominant in the Danish trade union movement. It is furthermore argued that flexicurity was on the verge to disappear when it became famous in the early 2000s, although yet not completely dead.     

Smooth investment

In the classical portfolio optimization problem considered by Merton, the resulting constant proportion investment plan requires a diffusive trading strategy. This means that, within any arbitrarily small time interval, the investor must impractically both buy and sell stocks. We study the problems of a mean-square and a power utility investor for whom the trading strategy is constrained to be smooth, i.e. nondiffusive. This means that over sufficiently small time intervals, the investor is either a seller or a buyer of stocks. The mathematical framework is built around quadratic objectives such that trading activity is punished quadratically. Mean-square utility is quadratic, and power utility is covered by quadratic punishment of distance to Merton’s power utility portfolio. We present semi-explicit solutions and, in a series of numerical illustrations, show the impact of trading constraints on the portfolio decision over the investment horizon.     

Baylor University Roundtable on The Corporate Mission, CEO Pay, and Improving the Dialogue with Investors

A small group of academics and practitioners discusses four major controversies in the theory and practice of corporate finance:

• • What is the social purpose of the public corporation? Should corporate managements aim to maximize the profitability and value of their companies, or should they instead try to balance the interests of their shareholders against those of “stakeholder” groups, such as employees, customers, and local communities?
• • Should corporate executives consider ending the common practice of earnings guidance? Are there other ways of shifting the focus of the public dialogue between management and investors away from near-term earnings and toward longer-run corporate strategies, policies, and goals? And can companies influence the kinds of investors who buy their shares?
• • Are U.S. CEOs overpaid? What role have equity ownership and financial incentives played in the past performance of U.S. companies? And are there ways of improving the design of U.S. executive pay?
• • Can the principles of corporate governance and financial management at the core of the private equity model—notably, equity incentives, high leverage, and active participation by large investors—be used to increase the values of U.S. public companies?

     

China’s Agricultural Policy Transition: Impacts of Recent Reforms and Future Scenarios

This article reviews recent developments in China’s agricultural domestic support policy, especially the transition from taxing farmers and agriculture to providing direct subsidies to grain production and purchased inputs. A model‐based quantitative analysis on the effects of these policy changes is presented. Simulation results suggest that recent policy changes have achieved the declared policy goals of increasing grain production and boosting farm income. Much of the increase in grain production and farm income can be attributed to higher per unit return to arable land, land reallocation to grain production and extra agricultural employment triggered by the policy changes. Based on the assumption that China’s public assistance to agriculture and farmers will continue and rise, two hypothetical future scenarios are simulated. Using all the support permitted under WTO de minimis limits with existing instruments, China’s policy will increase grain production, change trade patterns seemingly contrary to China’s comparative advantage, increase rural employment and significantly increase farm income (by more than 12%). If, however, decoupled instruments are applied to raise China’s agricultural domestic support to the same level, China’s agricultural production and trade will remain unchanged, rural employment remain stable, but farm income will be increased by nearly 15%.     

Bayesian semiparametric stochastic volatility modeling

This paper extends the existing fully parametric Bayesian literature on stochastic volatility to allow for more general return distributions. Instead of specifying a particular distribution for the return innovation, nonparametric Bayesian methods are used to flexibly model the skewness and kurtosis of the distribution while the dynamics of volatility continue to be modeled with a parametric structure. Our semiparametric Bayesian approach provides a full characterization of parametric and distributional uncertainty. A Markov chain Monte Carlo sampling approach to estimation is presented with theoretical and computational issues for simulation from the posterior predictive distributions. An empirical example compares the new model to standard parametric stochastic volatility models.     

Analysis of SMEs partner proximity preferences for process innovation

This paper explores small and medium enterprises’ (SMEs) proximity preferences when selecting partners for collaborative process innovation. Drawing on a survey of 362 Danish SMEs, we address four partner proximity characteristics: geographic, cognitive, organizational, and social. The results show that SMEs prioritize geographic openness over regional clustering. Furthermore, to simultaneously facilitate collaboration and ensure innovation, firms tend to collaborate with partners that are characterized by cognitive similarity at a technological level and knowledge distance at a market level. Technological proximity is also found to be more relevant than social proximity when it comes to bridging the potential geographic and market distance between the collaborative partners. Finally, the results indicate that the tendency of organizational proximity to facilitate informal interactions with partners enhances process innovation only at two of four process innovation levels. Thus, the results highlight the fact that the value of partner proximity characteristics change with the level of process innovation considered.     

von Thünen: Capital,Production Functions,Marginal Productivity Wages,and the Natural Wage

This paper puts seminal contributions to theory of production functions and maximization of explicit quantitative objective functions by Johann Heinrich von Thünen into a systematic historical perspective. We show that his comprehensive ‘Tableau Economiques’ do imply two exact parametric production functions. Moreover, the renowned ‘geometric mean wage’ formula is restated as an exact CES marginal labor productivity wage for σ = 2. We review four alternative modes of normative (natural) wage calculations without an explicit production function, and conclude that von Thünen's natural wage differentiation formulas are bona fide alternatives for deriving the natural wage formula.     

Comparing family changes in two rural areas of Kenya: Past legacies and present realities

ABSTRACT

Fertility in Kenya declined from total fertility rate (TFR) 6.7 to 4.6 between 1989 and 2008/09. Initially, Western and Coast Provinces returned figures above and below the national average with TFR 8.1 and 5.4 respectively. Then fertility in Western Province declined substantially to TFR 5.6 while in Coast Province the decline was modest to TFR 4.8, above the national average in both provinces. I shall scrutinise this development by examining two rounds of qualitative case studies in rural villages in the two provinces, first in 1988–90 with a follow up in 2011. The analysis revealed that over time fewer children were born in the Western villages, but more in the Coast villages. The hypothesis is that differences in cultural (patriarchy and a mix of matriarchy and patriarchy) and religious (Christian and Muslim) legacies are crucial to understanding such disparities in childbearing. Attention is given to marriage, gender relations and female education.
