  • タイトル:TFP Growth, Monetary Policy, and Inequality in Japan (with Nao Sudo)
  • アブストラクト: In this paper, we construct quarterly series of income and consumption inequality indices from the 1980s to 2000s and estimate how they react to a shock to TFP and conventional monetary policy using the local linear projection. Our empirical findings are
    summarized in the four points. (i) A favorable shock to TFP and to the short-term interest rate both increases income and consumption
    inequality indices. (ii) Both shocks affect a distribution at the bottom more than that at the top. (iii) For both shocks, “heterogeneous earning channel” seems to play an important. (iv) For both shocks, less than 50% of income inequality is transmitted to consumption inequality. Using a dynamic general equilibrium model with heterogeneous agents, we discuss implications of our empirical results
    to nature of linkage between macroeconomic shocks and inequality.

タイトル:”Understanding the Role of Public Employment Services: Theory and Empirical Evidence ” (with Christian Holzner)
Abstract:Using the German Job Vacancy Survey we are able to show how the Public Employment Services (PES) affect the labor market. Almost half of all vacancies in Germany are registered with the PES. The PES is shown to distribute workers more evenly among vacancies compared to the private market. Applicants send by the PES are on average less suited for the job than applicants attracted through the private market. The less suited pool of applicants and the reduction in coordination frictions is going along with lower wages paid by registered firms. We rationalize our empirical findings using a directed search model, where firms can decide whether to search via the PES or the private market. Lower coordination frictions in the PES induce less wage competition between firms enabling them to pay lower wages. The implicit cost of registering a vacancy is due to the less suited pool of applicants and explains why not all vacancies are registered with the PES despite the fact that its service is free of charge.

  • タイトル:"Structural Estimation on the Wage Dynamics Depending on the Labor Market Tightness in Japan"
  • Abstract: This study estimates structural parameters characterizing price and wage dynamics in Japan by taking the labor market tightness into account. In order to reveal a state-dependency of price and wage dynamics, we first estimate smooth transition vector autoregressive model in which unemployment rate is regarded as a transition variable. Thereafter, structural parameters in each state of the labor market are estimated using the impulse response matching technique. The results are summarized as follows. First, price and wage indexation in Japan is quite low. Second, as the labor market tighten, price becomes more sticky while wage becomes less sticky. Third, the standard theoretical model can describe the Japanese economy sufficiently at the period of the labor market being tight. As the labor market loosen, however, the distance between the empirical and theoretical responses gradually grows.

● Title: "
Spatio-temporal pattern formation in rent distribution: A case study for city of Sapporo"
● Abstract: 
We propose a very simple probabilistic model to explain the spatio-temporal structures of rent distribution in city of Sapporo. Here we modify the mathematical model proposed by Gauvin et. al. [1].  In their mathematical modeling, they utilized several assumptions to describe the decision making of each inhabitant in Paris. Namely, they assumed that the intrinsic attractiveness of a city depends on the location and there exists a single peak at the center. They also used the assumption that each inhabitant tends to choose the place where the other inhabitants having similar or superior income to himself/herself are living. In order to find the best possible (desirable) place to live,  each buyer in the system moves from one place to the other according to the transition (aggregation) probability described by the above two assumptions, and he/she makes a deal with the seller who presents the best possible condition for the buyer. They concluded that the resultant self-organized rent distribution is consistent with the corresponding empirical evidence in Paris. However, it is hard for us to apply their model directly to the other cities having plural centers (not only a single center as in Paris). Hence, here we shall modify the Gauvin's model to include the much more detail structures of the attractiveness by taking into account the empirical (aggregated) data concerning the housing situation in city of Sapporo. We also consider the competition between two distances, namely, the distance between house and center, and the distance between house and office. Computer simulations are carried out to reveal the self-organized spatial structure appearing in the rent distribution. We also compare the resulting distribution with empirical rent distribution in Sapporo as an example of cities designated by ordinance.
  In this talk, we present several findings such as
1) The lowest ranking agents (buyers) visit almost all of regions in city to look for their housing even though such places are highly `attractive places, whereas the highest ranking agents visit relatively high  attractive places.
2) The lowest ranking agents are swept away from attractive regions and make several their own `communities' in low offering price locations (the north-east area in Sapporo).
  We also discuss the possibility of the model to explain the distribution of land price in commercial area.

● Title: "Parietal-striatal network plays a role in translating cardinal reward information into ordinal utility"
● Abstract:  Since the Stiglitz Report was published in 2009, there has been much debate between economists and psychologists on the validity of happiness data as a policy target for economic issues. Here we provide novel biological evidence obtained from human fMRI experiments to help offer some answers to this cross-discipline debate. We found that when subjects expressed happiness with a monetary reward on an ordinal scale—a common method for collecting happiness data—the parietal–striatal network was involved in their evaluation of their happiness levels in accordance with the given scale. Because of the existence of this additional cognitive process, we suggest that conventional happiness data would be a noisy proxy of intrinsic cardinal utility.

Title: "
Competition in the Presence of Individual Demand Uncertainty"   (with Marc Möller)
● Abstract:  This paper sheds light on an empirical controversy about the effect of competition on price discrimination. We propose a model in which consumers learn their preferences over time and show that firms offer advance purchase discounts. Consumers choose between an early (uninformed) purchase at a low price and a late (informed) purchase at a high price. Competing firms offer higher discounts to secure a large market share in advance. Competition decreases welfare and may affect consumers negatively. The empirical finding, that competition may influence price dispersion positively or negatively, can be explained by differences in the level of demand uncertainty.
