Some evidence on the role of money illusion in labor supply behavior

The Keynesian idea that workers are subject to money illusion in their labor supply decisions is tested by estimating a labor supply function that includes the price level as an independent variable. The model is estimated with data drawn from various BLS publications and is aggregated by SMSA. The results indicate a significant negative supply response to price-level changes after controlling for the nominal wage rate, income, and the SMSA's unemployment rate. There is no significant difference between workers' supply response to the price level and the nominal wage rate, which suggests that workers are not subject to money illusion.     

New products or remanufactured products: Which is consumer-friendly under a closed-loop multi-level supply chain?

If the remanufactured and fresh products are in the market at the same price and quality, then it is difficult for the retailer to sell them all together simultaneously. There is differentiability in the market by the consumers even though they are of similar quality and price. These remanufactured products are the effect of a closed-loop supply chain. The closed-loop type supply chain problems have pulled much attention to tackling environmental and social issues for these remanufactured products. Based on the concern, a closed-loop formation of the supply chain is formulated with four players. Two types of quality are assigned for the manufactured and remanufactured products as remanufactured products maintain less quality than the newly manufactured products. The production system is imperfect, then all products are not perfect. A mathematical model with a multi-cycle closed-loop supply chain is discussed here, where the reworking process happens within the same cycle. An acceptance quality level influences the regaining rate of consumed products. The non-integrated phenomenon uses the inventory management policy operated by the vendor and the consignment-type stock policy. This mathematical problem is solved by employing algorithms, developed to achieve the local optimum (non-integrated situations) and global optimum (integrated situations). A numerical example and sensitivity analysis are provided to establish the mathematical model numerically. Results obtain that the retailer can tackle the situation in a proper way such that the closed-loop supply chain always is in profit. The profit is globally maximized, and the best results are obtained from different situations.     

最低收购价政策改革背景下小麦期货市场价格发现功能再检验

通过构建最低收购价政策影响下小麦期现货市场的价格传导机制的理论框架,并选取2015年我国小麦最低收购价政策改革前后两个时期各4年的周度数据,使用ADF单位根检验、Johansen协整检验、Granger因果关系检验和方差分解对最低收购价政策改革背景下小麦期货市场的价格发现功能进行实证研究。研究结果表明:无论是强麦还是普麦,最低收购价政策改革对于小麦期货价格与现货价格均衡关系的形成均具有促进作用;在最低收购价政策改革之前,强麦期货市场不具有价格发现功能,之后这种功能才得以形成,同时普麦期货市场的价格发现功能变得更为显著;小麦期货市场的影响力强于现货市场,在价格发现功能中占据主导作用。     

Optimal revenue-raising trade restrictions under uncertainty

A country seeks to achieve a fixed expected revenue by restricting trade when it faces uncertainty about domestic demand for a good and about foreign supply. If the uncertainty in the demand and supply functions is multiplicative then the policy which maximises domestic expected surplus is a fixed schedule of tariffs depending only on world price. Under additive uncertainty the ranking of ad valorem tariffs and quotas depends systematically on the targeted expected revenue and the degree of uncertainty in demand and in world price but a specific tariff is superior to both these policies.     

信用扩张的合理界限与房价波动研究

房地产业是资金密集型产业,它的供给与需求很大程度上由信用扩张程度来决定。而信用扩张的合理边界作为货币政策的目标,决定了房地产的繁荣程度与价格水平的高低。因此,货币政策对房价具有重要的影响。但是,由于所有的金融交易都存在着内在与外在的不稳定,这就需要一系列的金融制度安排来保证信用扩张边界的合理性。同样,由于金融制度不完全性、效应的滞后性及利益的渗透性,金融交易制度安排的缺陷可能成为房地产价格波动的制度性根源。由此,本文从货币政策的制度因素来讨论与研究信用扩张过度与房价的波动关系,并希望从中寻求对房价波动更为一般性的解释。     

Comparative dynamics in a life cycle theory of the firm

Important insights and contributions to the corporate financial manager's decision problem have been provided by the balanced-growth financial modeling literature, e.g., see [4, 5, 8, 10, 11, 13, 15]. In the spirit of this research, the objective of this paper is twofold. First, a normative model of the dynamic financial planning process in a deterministic environment is constructed wherein the traditional, steady-state assumptions are relaxed. In contrast to prior models, the firm is allowed to pay a liquidating dividend and faces a time-dependent investment rate of return, interest rate, and equity discount rate. Necessary and sufficient conditions for the levered firm's optimal investment-financing-dividend policy decisions which maximize the wealth of its investors are developed, and a solution synthesis technique is employed to catalogue the different decisions at each time instant in terms of three earnings-growth stages over the firm's life cycle. Over this life cycle, the firm experiences high, low, and negative growth stages, with the latter stage distinguished by a liquidating dividend payout and retirement of debt outstanding. Secondly, the life cycle depiction further permits an analysis of the effects, in terms of both direction and magnitude, on the optimal duration of the firm's different growth stages and optimal growth rates due to changes in the firm's return on investment, debt-equity ratio, borrowing rate, equity discount rate, depreciation rate, and flotation costs via a comparative dynamics and simulation framework. Changes in the return on investment are found to have the most influence on the duration of the firm's growth periods and their respective earnings growth rates, while changes in the mix of financing and depreciation rate tend to have the least effect. Furthermore, the magnitudinal impact of marginal changes in any of the above firm variables is greatest at low levels of debt-to-equity and growth-in-earnings and quickly dissipates as the degree of leverage increases.     

How Large Is the Risk of Stagflation in the Eurozone?

The rapid recovery of demand combined with supply constraints has led to rising prices during the past months. This is evident in oil and gas markets, but also in international trade, which has been thrown out of step by bottlenecks at Asian ports. This situation creates a trade-off for the European Central Bank, because a more expansionary monetary policy cannot mitigate the supply bottlenecks and supply-side restrictions, while a more restrictive monetary policy would slow down the economic recovery. For this reason, key interest rate hikes in the eurozone are not to be expected for 2022. If the supply-side factors become persistent and wage policy tries to pass the price effects on, monetary policy will be forced to become restrictive.

     

The Effect of Attribute Variation on Consumer Choice Consistency

We study the effect of shifts in attribute level differences on consumer choice consistency. Choice consistency is measured as the variance of the random error component in the consumer utility function: the smaller this variance, the higher choice consistency. We hypothesize that due to increased choice difficulty, choice consistency decreases if attribute level differences increase while average utility level differences between alternatives remain the same. In our empirical illustration we focus on the impact of price level shifts on choice consistency in conjoint choice experiments. Our results show that choice consistency decreases as price level differences increase and absolute price levels increase.     

农业生产资料价格对农民收入增长的影响——基于动态VAR模型的解释

本文在建立向量自回归模型的基础上考察1978年以来我国农业生产资料价格与农民收入增长之间的动态影响关系。并运用脉冲响应函数和预测方差的方法,得出农业生产资料价格的平稳增长与农民收入的增加存在并不矛盾的且长期稳定的正向交互响应作用的结论,从而为农业产品要素市场的宏观调控提供较准确的依据。     

中国能源消费因果关系分析

基于协整、误差修正模型与方差分解,分析我国1953年以来的能源消费与经济增长、能源价格、产业结构之间的Granger因果关系。实证结果表明:经济增长不是引起能源消费变化的原因,这可能是由于我国存在着严重的能源浪费造成的;而能源消费是引起经济增长的原因,这验证了我国过去50年高投资、高消耗的粗放式经济增长模式,近几年我国能源消费弹性系数的变化再次反映了这一问题。能源消费与能源价格不存在任何方向的因果关系,方差分解结果再次肯定了能源价格的相对外生性,这预示着政府若要增强能源价格对于能源消费的影响作用,必须放开对能源价格的管制,让市场主导能源价格的形成。产业结构是引起能源消费变化的重要原因,因此从产业结构方面入手调控能源消费将是非常有效的。     

中国宏观经济运行总量指标互动影响的实证研究

本文利用Granger因果关系检验及建立向量误差修正(VEC)模型,从数量上对中国宏观经济运行总量指标之间的相互影响及关系问题进行实证分析,结果表明物价水平、经济增长和固定资产投资之间存在显着的相互影响。从短期看,固定资产投资与经济增长均对物价水平存在着滞后、正向的推动作用。从长期看,当期投资将在未来期内转化为供给,在反方向上促使物价下滑,因而固定资产投资在长期内对物价水平存在着一个显着的反向影响力。而且广义货币供给量通过固定资产投资与经济总产出的传导作用,对物价水平发生影响。     

要素价格扭曲与经济失衡之间的互动关系研究

劳动力、资本、能源三种生产要素价格扭曲与宏观经济失衡之间存在互动关系。通过建立超越对数生产函数,估算改革开放以来中国劳动力、资本、能源三种生产要素价格的绝对和相对扭曲程度,继而建立VAR模型,考察各内生变量之间的脉冲响应关系。研究表明,要素价格扭曲和宏观经济失衡之间存在相互强化的互动关系。应从调整供给结构、增加政府民生支出、改革要素价格形成机制、提高生产效率等多方面着手,实现宏观经济再平衡。     

The equivalence of quotas and buffer stocks as alternative stabilization policies

The choice of an optimal policy when the foreign supply curve is unstable has been considered separately in two earlier articles. Both authors have shown that price stabization is welfare increasing if a tariff set for noneconomic reasons is above 100 percent. The fact that both achieve the same result despite the choice of different stabilization measures is taken up in this article. It is found that price stabilization through quotas or buffer stocks will have the same effect on economic welfare despite their differing impact on the level of imports under varying supply conditions.     

不完全汇率传递下的货币政策工具规则分析

本文尝试构建一个开放条件下的总供给-总需求模型,通过名义进口价格刚性在模型中引入汇率传递因素。模型对各种货币政策工具规则下社会福利损失函数进行比较,考察在不同的汇率传递程度下的各种货币政策工具规则。研究结果显示,社会福利水平随着汇率传递程度下降而提高;货币政策工具规则对消费者物价指数(CPI)上涨作出反应一定程度上优于对国内制造商品价格上涨作出反应,制定的货币政策工具规则应该以CPI为目标,以使社会福利损失最小。     

Optimal monetary-fiscal stabilizers under an indexed versus nonindexed tax structure

This article analyzes the optimal coordination of automatic monetary and fiscal stabilization parameters in a rational expectations context. Optimal joint settings for the average level of tax rates, the progressivity of the tax structure, and the response of the money stock to the current level of the interest rate are derived to minimize the variance of output and price.     

我国货币政策与沪深股市的协整关系研究

运用协整检验、误差修正模型、格兰杰(GRANGER)因果检验等计量经济学方法,对我国货币政策如何影响沪深股市这一问题做了系统而深入的研究。通过分析,得出了如下结论:STV、M0、M1、M2之间存在着两个协整关系;RSTV、RM0、RM1、RM2之间存在着三个协整关系。在货币供应量与沪深股市市价总值之间,是货币供应量的变化影响沪深股市市价总值,而不是沪深股市市价总值影响货币供应量的变化。这些结论对投资者尤其是机构投资者来讲,具有一定的参考价值。同时,对我国货币政策当局调控股市也有一定的借鉴意义。     

Improving the effectiveness of persuasive communications: Matching message with functional profile

The functional approach to improving communication strategy has received little attention. This research attempts to partially correct this oversight by experimentally verifying the major functional hypothesis: matching message with functional profile brings about attitude change. Working adults were integrated into an experiment which was a before-after with control. The major functional hypothesis was confirmed at the 0.10 level. An associated hypothesis regarding the relative ease of changing value- expressive attitudes compared to utilitarian attitudes was confirmed at the 0.10 level. The results show the importance of matching message with functional profile and highlight the potential inherent in the functional approach.     

我国化肥价格波动与农民收入关系的实证分析

本文利用1978～2008年的时间序列数据,运用脉冲响应函数和方差分解技术考察化肥价格波动与农民收入之间的关系,发现化肥价格的波动与农民收入变化之间存在着双向的因果关系,即化肥价格的上涨导致农民增收缓慢,而化肥价格上涨的根本原因在于＂需求拉动＂和＂成本推动＂。今后必须从需求和供给两方面采取对策：一方面通过建立化肥直接补贴制度和化肥储备制度,从需求上控制化肥价格上涨;另一方面通过采用新型化肥生产技术和给予化肥生产企业生产用能以优惠政策,从供给上控制化肥价格上涨。     

Is the online-offline buy-online-pickup-in-store retail strategy best among other product delivery strategies under variable lead time?

Every industry improves customer satisfaction by either preventing stockout situations or fulfilling the customer's demand by reducing lead time and variance of the lead time with several services offered. This study considers online selling, offline selling, and buy-online-pickup-in-store policies for selling products from retail stores. This study builds a characteristic relation between buy-online-pickup-in-store, backorder, and on-hand inventory by giving an exact total profit function instead of the expected profit function. The marginal values on lead time and variance of the lead time earn more exact outcomes for any retail strategy. The specific transportation cost for different retail strategies is considered and tested. This paper shows the analytical results which prove that the total profit of the sustainable supply chain is a convex function of both lead time and variance of the lead time. As different channel selling is crucial to any industry for increasing customer demand, the retailer sells their products by hybrid channel and advertises their products online to make them more famous. The model is solved through a classical optimization technique to get a semi-closed-form solution. In this method, it is possible to find out the optimum results for the decision variables separately by equating the first order partial derivative of the total profit with respect to the decision variables to zero and the global optimality by the Hessian matrix. A numerical experiment is conducted here, and the result shows that the supply chain system gives 14.48% more profit if advertisement policy is applied. The supply chain system gives 57.31% less profit and 72.72% less profit when only an online or offline channel is adopted, respectively. A sensitivity analysis is done for the managerial effects of cost parameters on the total profit.     

The impact of household level heterogeneity in reference price effects on optimal retailer pricing policies

The field of marketing has witnessed substantial improvement in modeling household level heterogeneity. However, relatively little has been written about how modeling household heterogeneity translates into better marketing decisions. In this paper, we study the impact of household level heterogeneity in reference price effects on a retailer's pricing policy. Reference prices are certain anchors or standards that households use to compare the observed purchase price of a product against. If the observed price is greater than the reference price it is perceived as a “loss” and if it is smaller than the reference price it is perceived as a “gain”. In order to study the impact of heterogeneity in reference price effects on retail pricing, we test a nested logit model under two alternative reference price (memory and stimulus based) and heterogeneity (finite mixture and hierarchical Bayes) specifications. In the empirical analysis, we find that households are quite heterogeneous in terms of their gain and loss effects. For some households a gain has higher impact than a corresponding loss, while the opposite is true for others. Using individual level estimates we then develop a normative pricing policy for a retailer maximizing category profit. Our results indicate that the optimal pricing policy derived from the heterogeneous case is qualitatively different, and more profitable, than the case when heterogeneity is ignored. We show that for an important marketing problem pertaining to a retailer, the optimal pricing decisions for various brands in a category are inextricably related to household heterogeneity in reference effects and brand preference.
