企业家们的新年祝福

商场在疯狂甩卖,其降幅和冷清堪比非典时期;出租车的空位多了,地铁公交却更拥挤了;公司的年终奖打折了,企业都在喊亏损;华尔街爆发危机了,全球的股市都在跌;公司晚会不办了,出国旅游取消了,皮草名车也不买了……经济危机真的来了。企业家们受影响了么?显然不会例外。央行行长的头发都白了,而更多企业家的头发都掉光了;有的企业家绝处逢生,东山再起,而有的从云端落下,光环尽失;有的企业家卷款逃     

技术进步的恐慌与诱惑

从上个世纪的80年代开始，我们感受到了前所未有的社会变化，人们的生活发生了巨变，以“芯片”作为主要电子元件的设备充斥着人类的生活。我们传输信息的速度加快了，我们收集、整理信息的速度也加快了，我们的管理水平提高了，我们工作的速度也提高了，我们对世界改变的速度也加快了。人们感受到了由于技术进步带来的好处，工资的待遇提高了，汽车、洋房增多了，人们所需的日常物品丰富了，人们休闲娱乐的方式增多了。人们的寿命增长了。

Gendered role modelling—A paradoxical construction process

Theory of role modelling in organizations addresses the contents of role models, while the process of modelling has received little attention. In this paper, this gendered process is scrutinized from a constructionist perspective. Modelling starts with a comparison between an image of oneself with that of a person who serves as a proto-model; continues with idealization and/or composition of the traits of proto-models resulting in an image of a role, and ends with a comparison between such an image and an image of oneself, leading to directives for action. People do not model their behaviour on real persons, but on mental constructs they make loosely inspired by actual people. This conclusion forms a new argument against tokenism: it is never enough to employ one woman, as proto-models must be many and varied.     

Estimating Mann–Whitney‐type Causal Effects

Mann–Whitney‐type causal effects are generally applicable to outcome variables with a natural ordering, have been recommended for clinical trials because of their clinical relevance and interpretability and are particularly useful in analysing an ordinal composite outcome that combines an original primary outcome with death and possibly treatment discontinuation. In this article, we consider robust and efficient estimation of such causal effects in observational studies and clinical trials. For observational studies, we propose and compare several estimators: regression estimators based on an outcome regression (OR) model or a generalised probabilistic index (GPI) model, an inverse probability weighted estimator based on a propensity score model and two doubly robust (DR), locally efficient estimators. One of the DR estimators involves a propensity score model and an OR model, is consistent and asymptotically normal under the union of the two models and attains the semiparametric information bound when both models are correct. The other DR estimator has the same properties with the OR model replaced by a GPI model. For clinical trials, we extend an existing augmented estimator based on a GPI model and propose a new one based on an OR model. The methods are evaluated and compared in simulation experiments and applied to a clinical trial in cardiology and an observational study in obstetrics.     

Sanov meets Cramér again

We introduce a new method for proving large-deviation principles (LDPs). This method amounts to "mixing" a collection of LDPs with a sequence of probability measures that obeys itself an LDP. As an illustration, we construct from empirical measures a sequence of capacity-valued maps that can be considered as an indexed collection of LDPs. The index 1 coincides with Sanov's theorem. By taking a Poisson mixture we establish a new connection with Cramér's theorem.

On Models with an Uncongestible Public Good and a Continuum of Consumers

This short note shows that models with an uncongestible or mildly congestible public good and a (non-atomic) continuum of consumers have an interesting but unfortunate property. Only an infinite level of public good provision in the continuum economy can be approximated by feasible public good levels in a sequence of economies with finite populations. We discuss the theoretical and practical problems this creates for familiar models that employ a continuum of consumers and a finite level of an uncongestible public good.     

A sharing mechanism of investment outcome for interest-sensitive life insurance products

As growing sales of insurance contracts with a saving feature, an issue of sharing investment outcome gets the attention of insurers and policyholders. This paper focuses on a systematic way of finding the sharing mechanism for an optimal contract design in such a way that a policyholder and an insurer maximize their expected utilities. We adopt the policyholder and the insurer as a principal and an agent, respectively, and regard a share of the investment performance as an incentive for the insurer to elicit efforts. As a result of this setting, the moral hazard issue generated from the insurer is unavoidable. For the purpose, the Holmström (1979)’s principal-agent model with limited observability of the insurer’s action plays a leading role in resolving a pie-cutting problem. Under our model assumption, the sharing mechanism states that a portion of the outcome belonging to the insurer is a nondecreasing function of the excess of the portfolio return over a benchmark return when the two parties are risk-averse. In particular, the sensitivity of the sharing portion has an S-shape curve which is consistent with the insurer’s risk propensity.An empirical study based on companies’ portfolio attributes and crediting rates verifies that our theoretical findings are consistent with statistically significant results. In particular, we confirm that the bargaining power of the insurer has a considerable impact on the sharing mechanism as it is theoretically important.     

Sustainable growth, renewable resources and pollution

Our intention is to present a growth model with an environmental resource which has its own regeneration process. The stock of this resource serves as a source of utility and an input to production. We also intend to introduce a negative externality caused by a pollution flow which we assume to be proportional to production. In the context of this model, it is shown that, by using the utility level of the Green Golden Rule as a generalization of the Ramsey's bliss point for solving an optimal growth problems with a zero discount rate, an optimal path converges to the Green Golden Rule configuration.     

Econometric analysis of linearized singular dynamic stochastic general equilibrium models

In this paper I propose an alternative to calibration of linearized singular dynamic stochastic general equilibrium models. Given an a-theoretical econometric model as a representative of the data generating process, I will construct an information measure which compares the conditional distribution of the econometric model variables with the corresponding singular conditional distribution of the theoretical model variables. The singularity problem will be solved by using convolutions of both distributions with a non-singular distribution. This information measure will then be maximized to the deep parameters of the theoretical model, which links these parameters to the parameters of the econometric model and provides an alternative to calibration. This approach will be illustrated by an application to a linearized version of the stochastic growth model of King, Plosser and Rebelo.     

Dynamic control of rural–urban migration

This study investigates the optimal urbanization control of an underdeveloped economy by specifying a simple dynamic rural–urban model in which the urban sector bears both an intertemporal positive externality and a simultaneous negative externality. The dynamic optimization problem is solved for the political intervention of the central government in an intersectoral population distribution with taxes and subsidies. Our analysis provides the following results: (i) a big-push policy that leads an economy to a higher-income steady state with urbanization is not necessarily desirable if the government cannot borrow money at a sufficiently low interest rate; (ii) in order to sustain an appropriate urbanization speed, urbanization control policy should have a switch: the urban sector should be subsidized in order to accelerate rural–urban migration in early stages of development, and taxed to decelerate and eventually cease the migration in later stages.
