Some unfamiliar dynamics of a familiar macro model a note

The idea that for small disturbances the full employment equilibrium is stable while for large disturbances it is unstable was coined by Leijonhufvud in the notion of a corridor. We discuss the existence of a corridor in the standard Keynesian-monetarist textbook macro-model. It turns out that though the full employment steady state of this model may be locally stable — which is the case when the well-known Cagan condition holds — the model is never globally stable. This is due to the inherent non-linearity in the demand for money function, arising from non-negativity of the nominal rate of interest. Thus, perhaps surprisingly, the Cagan condition is both necessary and sufficient for the existence of a corridor in the Keynesian-monetarist model.This note is adapted from a paper presented at the European Meeting of the Econometric Society, Bologna, August 1988. I would like to thank Søren Bo Nielsen and Peter Birch Sørensen (Copenhagen Business School), Thomas Lux (University of Bamberg), and two anonymous referees for helpful comments and suggestions. Remaining errors and shortcomings are mine.

Migrants' Savings, Purchasing Power Parity, and the Optimal Duration of Migration

If some of the returns to migration accrue from returnmigration, the optimal duration of migration may be shorter thanthe feasible duration of migration. We develop a model that providesand highlights conditions under which return migration takesplace even though a reversal of the inter-country wage differentialdoes not occur. In particular, we consider the higher purchasingpower of savings (generated from work abroad) at home than abroadas a motive for return migration. Inter alia, our model producesa negative relationship between the optimal duration of migrationand the purchasing power differential and in some (but not all)cases, a negative relationship between the optimal duration ofmigration and the wage abroad. In addition, and contrary to ourprior anticipation, our utility maximization analysis suggeststhat East-West migration will tend to be temporary while inter-EuropeanCommunity (or intra-West European) migration will likely be permanent.     

Voluntary disclosure and information asymmetry in Denmark

This paper examines if the level of voluntary disclosure affects information asymmetry for industrial companies listed on the Copenhagen Stock Exchange. Economic theory suggests that disclosing more information should lower the information asymmetry component of a firm's cost of capital [Leuz, C., & Verrecchia, R. E. (2000)]. The results indicate that voluntary disclosure is negatively associated with proxies for information asymmetry. The results are robust even after controlling for various firm characteristics introduced in related literature. Despite differences in institutional settings the findings in our paper are similar to the ones based on US data.     

An Empirical Study of Firm Size and Competitiveness in German Life Insurance

Based on a purely rank-oriented approach, this empirical study analyzes to what extent superior firm size in German life industry generally translates into corporate advantages for the companies concerned. It turns out that while modest advantages with some criteria are measurable, any such benefits are usually outweighed by unquantifiable factors unrelated to firm size. Confining the study to a highly homogeneous subgroup of life insurers, however, reveals substantial corporate advantages in a number of areas, thereby confirming well-established theoretical reasoning.     

Simple Identification and Specification of Cointegrated Varma Models

We bring together some recent advances in the literature on vector autoregressive moving‐average models, creating a simple specification and estimation strategy for the cointegrated case. We show that in this case with fixed initial values there exists a so‐called final moving‐average representation. We prove that the specification strategy is consistent. The performance of the proposed method is investigated via a Monte Carlo study and a forecasting exercise for US interest rates. We find that our method performs well relative to alternative approaches for cointegrated series and methods which do not allow for moving‐average terms.

Tourism,changing architectural styles,and the production of place in Itacaré, Bahia,Brazil

This article examines changing architecture in Itacaré, Brazil, as it transitions from a fishing village to an international tourist destination. Tourism, as an assemblage of practices and perspectives, recreates places in specific ways that structure social and environmental relationships. Through an examination of historical architectural styles, tourist architecture, and popular architecture in Itacaré, this article analyses the ways a tourist economy has physically and socially rebuilt the city. Socially, the changing architecture marks and creates differences between class, racial, and regional identities while also providing an idiom through which public conversations about these changing economic systems and demographics are articulated. At the same time, the expansion of the city has led to racial-, regional-, and class-based segregation. Environmentally, tourist architecture creates new relationships to nature through re-imagining Itacaré’s position in relation to other rural and urban places and a new emphasis on the aesthetic value of nature.     

The systematic risk of corporate bonds: default risk,term risk,and index choice

In this paper, we empirically examine the systematic risk of corporate bonds in the Euro area. Based on a unique sample of 784 bonds from 1999 to 2010, we show that the systematic risk of constructed bond portfolios and individual bonds—measured against three different market indices—depends on credit quality, term risk, and index choice. A significant increase in systematic risk for lower-rated bonds is observed following the start of the financial crisis. In multi-factor models, bond portfolios load significantly on default and term risk, which are included as additional factors. Conducting Fama and MacBeth cross-sectional tests, we find that default and term risk are priced with economically relevant premiums that range from 0.35 to 0.62 % per month. Our results are robust to the inclusion of characteristics such as rating and time to maturity.
