Household borrowing and metropolitan housing price dynamics – Empirical evidence from Helsinki

This article argues that, especially in the absence of sufficient direct data on credit constraints, it is reasonable to add a household debt variable in an empirical model studying housing price dynamics. This is because household borrowing is likely to reveal information regarding the credit constraints faced by households. Moreover, debt may also give information on expected income growth and interest rate movements. The aim of this study is to examine empirically if household borrowing data, indeed, is of importance in a dynamic housing price model. In line with the prior expectations, it is found that housing appreciation in the Helsinki Metropolitan area is Granger caused by the household debt-to-GDP ratio both in the short and in the long run. Causality from the housing market to credit, in turn, seems to run only through a cointegrating long-run relation. While the estimated long-run relation between housing prices, income and debt-to-GDP ratio appears to have remained stable through the sample period (1975Q1-2006Q2), the short-run dynamics changed somewhat due to the financial liberalization in the late 1980s. The stability of the long-run relation implies that the loan data are able to cater, at least to a notable extent, for the effect of the changes in Finnish households’ liquidity constraints on housing demand. In line with previous literature, it is also found that housing price adjustment is sluggish and includes notable backward-looking features.     

The target projection dynamic

We study the target projection dynamic, a model of learning in normal form games. The dynamic is given a microeconomic foundation in terms of myopic optimization under control costs due to a certain status-quo bias. We establish a number of desirable properties of the dynamic: existence, uniqueness and continuity of solution trajectories, Nash stationarity, positive correlation with payoffs, and innovation. Sufficient conditions are provided under which strictly dominated strategies are wiped out. Finally, some stability results are provided for special classes of games.     

Managerial capital,occupational choice and inequality in a global economy

This study proposes a simple theory of trade with endogenous firm productivity, occupational choice and income inequality. Individuals with different managerial talent choose to become entrepreneurs or workers. Entrepreneurs enhance firm productivity by investing in managerial capital. The model generates three income classes: low‐income workers facing the prospect of unemployment, middle‐income entrepreneurs managing domestic firms and high‐income entrepreneurs managing global firms. Trade liberalization policies raise unemployment and improve welfare. A reduction in per‐unit trade costs raises top incomes and generates labour‐market polarization. A reduction in fixed exporting costs has an ambiguous effect on top incomes and personal income distribution. Policies reducing labour‐market frictions or the costs of managerial‐capital acquisition create more jobs and improve welfare. The income distributional effects of labour‐market policies depend on which policy is implemented.     

Reassessing the empirical validity of the human-capital augmented neoclassical growth model

We reassess Mankiw, Romer and Weil's [mrw] version of the Solow model using, as did mrw, cross-sectional data to estimate the steady-state equation governing income per capita levels. The model fails in two critical areas. First, plausible factor shares obtained by mrw are not robust to the substitution of two measures of human capital that are more precise than the secondary school enrollment rates used by mrw. Second, the null hypothesis of an exogenous and identical level of technology in all countries is rejected. We also explain why the Solow model performed well despite the above shortcomings.     

Academic entitlement and its relationship with perception of cheating ethics

Cheating is an epidemic in higher education. The author examined the psychological variable of academic entitlement and its relationship with the ethical perception of cheating using a sample of business students. Contrary to some previous research, the author found that millennials were only slightly more academically entitled than students from other generations but overall had a low sense of entitlement. Highly entitled business students viewed cheating actions as less unethical compared with less entitled students.     

Rent Protection as a Barrier to Innovation and Growth

We build a model of R&D-based growth in which the discovery of higher-quality products is governed by sequential stochastic innovation contests. We term the costly attempts of incumbent firms to safeguard the monopoly rents from their past innovations rent-protecting activities. Our analysis (1) offers a novel explanation of the observation that the difficulty of conducting R&D has been increasing over time, (2) establishes the emergence of endogenous scale-invariant long-run innovation and growth, and (3) identifies a new structural barrier to innovation and growth. We also show that long-run growth depends positively on proportional R&D subsidies, the population growth rate, and the size of innovations, but negatively on the market interest rate and the effectiveness of rent-protecting activities. An unpublished version of this paper was circulated earlier under the title “Innovation and Rent Protection in the Theory of Schumpeterian Growth.” We thank an anonymous referee and seminar participants in several venues for useful comments and suggestions.     

Gradual Product Replacement,Intangible-Asset Prices and Schumpeterian Growth

The paper develops a general-equilibrium model of scale-invariant Schumpeterian (R&D-based) growth. New higher-quality products are discovered through stochastic and sequential R&D races in each industry. The market share of an R&D race winner increases gradually and is governed by an exponential deterministic process. The introduction of gradual (as opposed to instantaneous) product replacement sheds more light on the effects of the rate of technology diffusion on long-run growth and on long-run dynamics of intangible asset prices. An economy with faster product diffusion rates experiences higher long-run innovation rates, faster transitional growth, and is populated by younger firms. As the typical firm becomes older, the earnings yield (i.e., the inverse of the price earnings (P/E) ratio) increases and expected earnings growth declines. Younger firms have lower earnings, lower market shares, but higher P/E ratios and higher expected earnings growth associated with their higher potential market growth.An electronic version of the paper is available at http://bear.cba.ufl.edu/dinopoulos/research.html.     

Analysing the stakes of stakeholders in research and development project management: a systems approach

Research and development (R&D) project management involves managing multiple stakeholders with conflicting stakes. This article proposes a systems approach to capture such conflicting stakes of multiple stakeholders in controversial R&D projects. The approach is illustrated using a New Zealand case study related to the use of 1080 chemical for pest management. Initially, the problem situation was structured systemically by analysing the behaviour of the main variables and by conducting a stakeholder analysis. Further, a participative systems model related to the problem situation was developed using a group model‐building process. The analysis of the model revealed a set of feedback loops operating in the system identified as constituting and responsible for the complexity of the problem situation relating to 1080 use. In conclusion, the paper highlights some strategies suggested by the stakeholders to manage conflict.     

Convolution of uniform distributions and ruin probability

Abstract

This paper presents an “operational calculus” method for evaluating the convolution of uniform distributions and applies it to solve a problem in ruin theory.
