The Effect of Marriage on Education of Immigrants: Evidence from a Policy Reform Restricting Marriage Migration*

We investigate the effect of immigrants’ marriage behavior on dropout from education. To identify the causal effect, we exploit a recent Danish policy reform that generated exogenous variation in marriage behavior by a complete abolishment of marriage migration for immigrants below 24 years. The reform influenced immigrants from countries with a high historical rate of marriage migration more than immigrants from country groups with a low rate. We find that the dropout rate for males increases by 25 percentage points as a consequence of marriage to a marriage migrant, whereas the effect for females is small and mostly insignificant.     

Monetary Policy in the Greenspan Era: A Time Series Analysis of Rules vs. Discretion*

Relationships between the Federal funds rate, unemployment, inflation and the long‐term bond rate are investigated with cointegration techniques. We find a stable long‐term relationship between the Federal funds rate, unemployment and the bond rate. This relationship is interpretable as a policy target because deviations are corrected via the Federal funds rate. Deviations of the actual Federal funds rate from the estimated target give simple indications of discretionary monetary policy, and the larger deviations relate to special episodes outside the current information set. A more traditional Taylor‐type target, where inflation appears instead of the bond rate, does not seem congruent with the data.     

Avoiding the loss of a gain: Retaining top managers in an acquisition

The turnover of management following a merger or acquisition is a significant, yet understudied, human resource issue. We propose that the relevant HR question is not merely how to retain top managers, but of equal importance, whether or not top management retention should be an objective. We present a model that integrates the retention process with the overall integration strategy being pursued by the acquiring firm. The model prompts a discussion of those factors that influence the decision as to whether the top management of the acquired firm should be retained. We conclude by identifying appropriate HR tactics for managing the retention process.     

The causal effect of board size in the performance of small and medium-sized firms

Empirical studies of large publicly traded firms have shown a robust negative relationship between board size and firm performance. The evidence on small and medium-sized firms is less clear; we show that existing work has been incomplete in analyzing the causal relationship due to weak identification strategies. Using a rich data set of almost 7000 closely held corporations we provide a causal analysis of board size effects on firm performance: We use a novel instrument given by the number of children of the chief executive officer (CEO) of the firms. First, we find a strong positive correlation between family size and board size and show this correlation to be driven by firms where the CEO’s relatives serve on the board. Second, we find empirical evidence of a small adverse board size effect driven by the minority of small and medium-sized firms that are characterized by having comparatively large boards of six or more members.     

Second thoughts on free riding

We use the strategy method to classify subjects into cooperator types in a large-scale online Public Goods Game and find that free riders spend more time on making their decisions than conditional cooperators and other cooperator types. This result is robust to reversing the framing of the game and is not driven by cognitive ability, confusion, or natural swiftness in responding. Our results suggest that conditional cooperation serves as a norm and that free riders need time to resolve a moral dilemma.     

Reintegrating Ethics and Institutional Theories

Organizational ethics and institutional theories are extended by recovering Weberian and Pre-Weberian theorizing that emphasized the joining of ethics and institutional theories. Understanding how ethics and institutional systems influence each other can advance our understanding of the nature and causes of structural organizational ethics issues and help guide potential reforms. We consider the interplay of these elements during the recession of 2008–2009, highlighting how structural ethics problems may have to be addressed at the institutional levels and not solely the individual or organizational levels.     

On the relationship between female labour force participation and fertility in G7 countries: evidence from panel cointegration and Granger causality

This article examines the relationship between the female labour force participation rate and total fertility rate for the G7 countries from 1960 to 2006 using panel unit root, panel cointegration, Granger causality and long-run structural estimation. The article’s main findings are that the female labour force participation rate and total fertility rate are cointegrated for the panel of G7 countries; that long-run Granger causality runs from the total fertility rate to the female labour force participation rate and that a 1% increase in the total fertility rate results in a 0.4% decrease in the female labour force participation rate for the G7 countries.     

International market integration and demand: An analysis of the Norwegian and Danish herring market

This article provides a method where pre-tests for international market integration are used to identify market structures before estimating demand systems. The method is applied to the analysis of the European herring market. A Vector Auto Regressive model in Error Correction form is used to identify co-integration vectors between price series and, based on this, to test for the Law of One Price. The Law of One Price is in force between the landing markets for herring in the two largest global supplier countries, Norway and Denmark. Therefore, an inverse demand function is estimated for the combined Norwegian and Danish market. The results are used in the interpretation of the significant increase in the prices of herring on the Danish ex-vessel market in 2001, given the stability of the Danish market. The implication is that even though Denmark did not export to the main Norwegian export markets in the former Soviet Union and Eastern Europe, the Danish landing price is influenced by the situation there.     

Reserves and cash flows under stochastic retirement

Uncertain time of retirement and uncertain structure of retirement benefits are risk factors for life insurance companies. Nevertheless, classical life insurance models assume these are deterministic. In this paper, we include the risk from stochastic time of retirement and stochastic benefit structure in a classical finite-state Markov model for a life insurance contract. We include discontinuities in the distribution of the retirement time. First, we derive formulas for appropriate scaling of the benefits according to the time of retirement and discuss the link between the scaling and the guarantees provided. Stochastic retirement creates a need to rethink the construction of disability products for high ages and ways to handle this are discussed. We show how to calculate market reserves and how to use modified transition probabilities to calculate expected cash flows without significantly more complexity than in the traditional model. At last, we demonstrate the impact of stochastic retirement on market reserves and expected cash flow in numerical examples.
