Accounting for Option–based Compensation: The Economic Cost Approach

The intrinsic value approach amortizes over the life of the option, the difference between the stock price on the date of the grant and the exercise price of the option. The fair market value approach amortizes over the life of the option, the market value of stock options on the date of the grant. These approaches do not reflect the changes in the option–based compensation cost after the grant date. This paper proposes an economic cost approach that not only adjusts for the changes in the value of the options during its life but also records the issuance of the stock at fair market value on the exercise date.     

Replacement Investment: Optimal Economic Life Under Uncertainty

Replacement investment is essentially a regenerative optimal stopping problem; that is, the key decision concerns when to terminate the life of existing plant – and hence when to start over again. This paper examines this optimisation problem within a continuous time framework and studies the qualitative and quantitative impact of uncertainty on the timing of new investment (and the criteria that should be used for terminating the life of existing plant).     

Tax Base and Crowding‐in Effects of Balanced Budget Fiscal Policy

A dynamic general equilibrium business cycle model is constructed with staggered price adjustment, monopolistic wage setting and distortionary taxation. The government purchases goods, runs an unemployment benefit system and balances its budget through a proportional tax on labour income. A temporary tax‐financed increase in government expenditures can lower the tax rate through a demand‐induced widening of the tax base. It is shown analytically that this allows private consumption to rise, under realistic conditions, despite the negative wealth effect of increased fiscal spending.     

Are We Better Off if Our Politicians Have More Information?

The model of public policy studied in this paper has heterogeneous citizens/voters and two public goods: one (roads) chosen directly by an elected policy‐maker, and the other (pollution) stochastically dependent on the amount of roads. Both a one‐country and a two‐country version of the model are analyzed; the latter displays externalities across the countries which create incentives for free riding and strategic delegation. The welfare effects of providing the policy‐maker with information about the relationship between roads and pollution are investigated, and it is shown that more information hurts some—sometimes even all—citizens. In particular, the opportunity not to create an institution for information gathering can serve as a commitment device for a country, although with the unfortunate effect of making the overall outcome even worse. Implications for the welfare effects of “informational lobbying” are also discussed.

On Sraffa's Standard commodity: is its price invariant with respect to changes in income distribution?

In his 1960 book, Sraffa suggested using a composite commodity,which he called the ‘Standard commodity’, to solveRicardo's search for an invariable measure of value, i.e., astandard capable of isolating the price movements of any othercommodity induced by changes in income distribution. The absencein Sraffa's book of an explicit proof of the invariance propertyof this standard gave rise to many misunderstandings about itsmeaning and its role as an invariable measure of value. In orderto clear up these questions, Bellino (On Sraffa's Standard commodity,Cambridge Journal of Economics, vol. 28, 121–32, 2004)has proposed a ‘proper’ definition of an ‘invariablemeasure of value’, showing that Sraffa's Standard commoditydoes fulfil the requirements of this definition. He claims thatthe fulfilment of this property (but not the constancy of its‘nominal’ price) qualifies the Standard commodityas an invariable measure of value. In this paper, a proof ofthe invariance of the price of the Standard commodity with respectto changes in income distribution is given, and the equivalenceof this property with Bellino's definition of invariance isshown.     

Glamour and Value Strategies on the Tokyo Stock Exchange

This paper evaluates the performance of glamour and value strategies and tests the extrapolation model for the Japanese equity market. In general, value stocks outperform glamour stocks by between 6 and 12 percent per annum for the five years after portfolio formation. Evidence from past, future and expected growth provides strong support for the story developed in Lakonishok, Shleifer and Vishny (1994). It is difficult to attribute the value premia to the difference, if any, in risk factors. In addition, the book-to-market premium is much closer to an arbitrage opportunity than the size premium.

直播电商中饥饿营销对消费者冲动购买行为的影响

饥饿营销在直播中应用非常广泛,但直播中饥饿营销影响消费者冲动购买因素的研究尚较缺乏。利用SOR（刺激-有机体-反应）理论构建结构方程模型,采用调查问卷的形式收集数据,并通过SPSS19.0和Amos 22对数据进行分析。研究表明：主播特质、在线评论、促销激励、促销数量限制对感知价值有显著正向影响;促销时间限制对感知价值的影响不显著;促销时间限制和促销数量限制对感知竞争性有显著正向影响;感知价值和感知竞争性对消费者冲动购买行为有显著正向影响。
