Stock Prices and the Real Economy: Power Law versus Exponential Distributions

This paper explores the relationship between the stock prices and the real economy. The standard approach – the so called consumption-based asset pricing model – attempts to explain it based on the assumption of the representative agent. In this paper, we argue that the representative agent assumption is fundamentally flawed. Drawing on the recent advancement of “econophysics” on financial markets See Mantegna and Stanley (An Introduction to econophysics: correlations and complexity in finance, 2000) for the introduction to econophysics, we argue that in contrast to the neoclassical view, there is in fact a wedge between financial markets, the stock prices in particular, and the real economy.     

Implementation of multi-agent incentive contracts with the principal's renegotiation offer

The purpose of this paper is to explore a mechanism for supporting desired equilibrium actions in a one-principal, multi-agent model when the principal makes a renegotiation offer. We show that there exists a mechanism in which the principal's most preferred mixed strategy is always supported. Received: 30 May 1997 / Accepted: 10 October 1998     

A trend filtering method closely related to $$\ell _{1}$$ trend filtering

The filtering method developed by Kim et al. (SIAM Rev 51:339–360, 2009), \(\ell _{1}\) trend filtering, is attractive because it enables us to estimate a continuous piecewise linear trend. This paper introduces a new filtering method closely related to \(\ell _{1}\) trend filtering in order to contribute to the accumulation of knowledge on \(\ell _{1}\) trend filtering. We show that the piecewise linearity, which is the key feature of \(\ell _{1}\) trend filtering, is derived from the new filtering. For this reason, we refer to the filtering as ‘pure’ \(\ell _{1}\) trend filtering. We also demonstrate some other miscellaneous results concerning the new filtering.     

The government expenditure–economic growth relation in Japan: an analysis by using the ADL test for threshold cointegration

Based on annual data from Japan for the period 1960 to 2010, we investigate the government expenditure–economic growth relation in Japan by using the autoregressive distributed lag test for threshold cointegration developed by Li and Lee (2010). In particular, we evaluate the validity of Wagner’s view and the Keynesian view in the case of Japan. The empirical results presented herein indicate that of these two classical economics perspectives, only Wagner’s view holds for Japan. The findings also demonstrate that the adjustment process towards its long-run equilibrium is asymmetric.     

Which is better for durable goods producers,exclusive or open supply chain?

We explore the supply chain problem of a downstream durable goods monopolist, who chooses one of the following trading modes: an exclusive supply chain with an incumbent supplier or an open supply chain, allowing the monopolist to trade with a new efficient entrant in the future. The expected retail price reduction in the future dampens the profitability of the original firms. An efficient entrant's entry magnifies such a price reduction, causing a further reduction of original firms' joint profits. In equilibrium, the downstream monopolist chooses the exclusive supply chain to escape further price reductions, although it expects efficient entry.     

Anticipatory effects of voluntary export restraints: a study of home video cassette recorders market, 1978-86

This paper investigates the impact of voluntary export restraints (VERs) at the pre-implementation stage when exporters have a good prospect for the VERs. Distinctive features of the VCR market in 1978-86 provide a testable hypothesis to analyze the effect of the EC-Japan VERs, which were implemented in the fiscal years of 1983-85. The paper finds consistent evidence that the VERs affected firms’ pricing behavior in the U.S. market prior to the VER period, as a result of Japanese exporters’ anticipation of the VERs.
