Throughout the 1990s, the supply of new condominiums in Tokyo significantly increased while prices persistently fell. This article investigates whether the market power of condominium developers is a factor in explaining the outcome in this market and whether there is a relationship between production cost trend and the degree of market power that the developers were able to exercise. In order to respond to these questions, we construct and structurally estimate a dynamic durable goods oligopoly model of the condominium market – one incorporating time-variant costs and a secondary market – using a nested GMM procedure. We find that the data provide no evidence that firms in the primary market have substantial market power in this industry. Moreover, the counterfactual experiment provides evidence that inflationary and deflationary expectations on production cost trends have asymmetric effects to the market power of condominium producers. The increase in their markup when cost inflation is anticipated is significantly higher than the decrease in the markup when the same magnitude of cost deflation is anticipated.

Should the central bank target asset price inflation? In their 1999 paper Bernanke and Gertler claimed that price stability and financial stability are “mutually consistent objectives” in a flexible inflation targeting regime which “dictates that central banks … should not respond to changes in asset prices.” This conclusion is straightforward within their framework in which asset price inflation shows up as a factor “augmenting” the IS curve. In this chapter, we pursue a different modeling strategy so that, in the end, asset price dynamics will be incorporated into the NK Phillips curve. We put ourselves, therefore, in the best position to obtain a significant stabilizing role for asset price targeting. It turns out, however, that inflation volatility is higher in the asset price targeting case. After all, therefore, targeting asset prices may not be a good idea.

Quality Function Deployment (QFD) proposes to take into account the “voice of the customer,” through a list of customer needs, which are (qualitatively) mapped to technical requirements in House One. But customers do not perceive products in this space, nor do they not make purchase decisions in this space. Marketing specialists use statistical models to map between a simpler space of customer perceptions and the long and detailed list of needs. For automobiles, for example, the main axes in perceptual space might be categories such as luxury, performance, sport, and utility. A product’s position on these few axes determines the detailed customer requirements consistent with the automobiles’ position such as interior volume, gauges and accessories, seating type, fuel economy, door height, horsepower, interior noise level, seating capacity, paint colors, trim, and so forth. Statistical models such as factor analysis and principal components analysis are used to describe the mapping between these spaces, which we call House Zero.

This paper focus on House One. Two important steps of the product development process using House One are: (1) setting technical targets; (2) identifying the inherent tradeoffs in a design including a position of merit. Utility functions are used to determine feature preferences for a product. Conjoint analysis is used to capture the product preference and potential market share. Linear interpolation and the slope point formula are used to determine other points of customer needs. This research draws from the formal mapping concepts developed by Nam Suh and the qualitative maps of quality function deployment, to present unified information and mapping paradigm for concurrent product/process design. This approach is the virtual integrated design method that is tested upon data from a business design problem.

How do stock prices evolve over time? The standard assumption of geometric Brownian motion, questionable as it has been right along, is even more doubtful in light of the recent stock market crash and the subsequent prices of U.S. index options. With the development of rich and deep markets in these options, it is now possible to use options prices to make inferences about the risk-neutral stochastic process governing the underlying index. We compare the ability of models including Black–Scholes, naïve volatility smile predictions of traders, constant elasticity of variance, displaced diffusion, jump diffusion, stochastic volatility, and implied binomial trees to explain otherwise identical observed option prices that differ by strike prices, times-to-expiration, or times. The latter amounts to examining predictions of future implied volatilities.

Certain naïve predictive models used by traders seem to perform best, although some academic models are not far behind. We find that the better-performing models all incorporate the negative correlation between index level and volatility. Further improvements to the models seem to require predicting the future at-the-money implied volatility. However, an “efficient markets result” makes these forecasts difficult, and improvements to the option-pricing models might then be limited.

This well-planned research is in tune with the times. ¹ Five of the postulates are called imperatives. They are indeed persuasive objectives. The remaining postulates deal with means for attaining those goals. Another word for postulate is assumption. Both words refer to ideas that we cannot know as facts of business life, and yet are needed as a basis for discussing accounting principles. Perhaps, therefore, they may be considered as compact verbalizations of basic concepts serving as foundational stones beneath accounting technology.

The essay studies the introduction and use of audio-visual media in contemporary Swedish courtroom praxis and how this affects social interaction and the constitution of judicial space. The background to the study is the increasing use of video technology in law courts during the last decennium, and in particular the reformed trial code regulating court proceedings introduced in Sweden in 2008. The reform is called A Modern Trial (En modernare rättegång, Proposition 2004/05:131). An important innovation is that testimonies in lower level court proceedings now are video recorded and, in case of an appeal trial, then are screened in the appellate court. The study of social interaction and the constitution of judicial space in the essay is based in part on an ethnographic study of the Stockholm appellate court (Svea hovrätt) conducted in the fall 2010; in part on a study of the preparatory works to the legal reform; and in part on research on how media technology affects social interaction and the constitution of space and place.
