Efficient Portfolios When Housing Needs Change Over The Life Cycle

We address the issue of the efficiency of household portfolios in the presence of housing risk. We treat housing stock as an asset and rents as a stochastic liability stream: over the life-cycle, households can be short or long in their net housing position. Efficient financial portfolios are the sum of a standard Markowitz portfolio and a housing risk hedge term that multiplies net housing wealth. Our empirical results show that net housing plays a key role in determining which household portfolios are inefficient. The largest proportion of inefficient portfolios obtains among those with positive net housing, who should invest more in stocks.

This is an open access book. As a leading role in the global megatrend of scientific innovation, China has been creating a more and more open environment for scientific innovation, increasing the depth and breadth of academic cooperation, and building a community of innovation that benefits all. These endeavors have made new contribution to globalization and creating a community of shared future. With the rapid development of modern economic society, in the process of economic management, informatization has become the mainstream of economic development in the future. At the same time, with the emergence of advanced management technologies such as blockchain technology and big data technology, real market information can be quickly obtained in the process of economic management, which greatly reduces the operating costs of the market economy and effectively enhances the management level of operators, thus contributing to the sustained, rapid and healthy development of the market economy. Under the new situation, the innovative application of economic management research is of great practical significance. 2022 International Conference on Bigdata, Blockchain and Economic Management (ICBBEM 2022) will be held on March 25–27, 2022 in Wuhan, China. ICBBEM 2022 will focus on the latest fields of Bigdata, Blockchain and Economic Management to provide an international platform for experts, professors, scholars and engineers from universities, scientific institutes, enterprises and government-affiliated institutions at home and abroad to share experiences, to expand professional fields, to exchange new ideas face to face, to present research results, and to discuss the key challenging issues and research directions facing the development of this field, with a view to promoting the development and application of theories and technologies in universities and enterprises.

In this paper we address the issue of the efficiency of household portfolios in the presence of housing risk. We present a theoretical model in which housing needs are age-dependent but exogenously determined, and consumers choose whether to rent or own the corresponding housing stock. Consumers also decide their consumption of a non-durable good and their financial investment strategies. They can invest in a risk-less asset (that includes human capital) and n risky financial assets. If the rental value of housing has a positive correlation with house prices, owning is a hedge against rent risk. When this correlation is unitary, we show that efficient financial portfolios should be the sum of a standard Markowitz portfolio and of a hedge term. This hedge term is a function of the correlations between housing and financial assets returns and multiplies the difference between the value of the housing stock owned and the present value of current and future housing needs.In our application we use Italian household portfolio data and time series data on financial assets and housing stock returns. Our empirical results support the view that the presence of housing risk plays a key role in determining whether household portfolios are efficient. They also highlight the need to distinguish between households who are long on housing (homeowners whose housing needs are declining) or short on housing (tenants and homeowners whose housing needs are still increasing).

This paper studies the impact of the portfolio constraint imposed by the consumption demand for housing (the 'housing constraint') on the household's optimal holdings of financial assets. Since the ratio of housing to net worth declines as the household accumulates wealth, the housing constraint induces a life-cycle pattern in the portfolio shares of stocks and bonds. For reasonable degrees of risk aversion, the changes in portfolio composition over the life-cycle can be dramatic. For example, for a coefficient of relative risk aversion of 3, the ratio of stocks to net worth in the optimal portfolio is .09 for the youngest households (ages 18-30) and .60 for the oldest (age 70 and over). Using data from the PSID on home values to construct household level panel data on the real after-tax return to owner-occupied housing, as well as data on the returns to financial assets, the paper estimates the vector of expected returns and the covariance matrix for the set of assets consisting of housing, mortgages, stocks, Treasury bonds, and T-bills. Numerical methods are used to calculate the mean-variance efficient frontier, conditional on different values of the housing constraint, and the optimal portfolios associated with different levels of relative risk aversion

Forecasts predict that those in need of long-term care in Europe will double in the next 50 years. This book offers a full understanding of the institutional responses and mechanisms in place to finance old age and provides analysis of demand and supply factors underpinning the development of financial instruments to cover long-term care in Europe.

Diversification provides a well-known way of getting something close to a free lunch: by spreading money across different kinds of investments, investors can earn the same return with lower risk (or a much higher return for the same amount of risk). This strategy, introduced nearly fifty years ago, led to such strategies as index funds. What if we were all missing out on another free lunch that’s right under our noses? InLifecycle Investing, Barry Nalebuff and Ian Ayres-two of the most innovative thinkers in business, law, and economics-have developed tools that will allow nearly any investor to diversify their portfolios over time. By using leveraging when young-a controversial idea that sparked hate mail when the authors first floated it in the pages ofForbes-investors of all stripes, from those just starting to plan to those getting ready to retire, can substantially reduce overall risk while improving their returns. InLifecycle Investing, readers will learn How to figure out the level of exposure and leverage that’s right foryou How the Lifecycle Investing strategy would have performed in the historical market Why it will work even if everyone does it Whennotto adopt the Lifecycle Investing strategy Clearly written and backed by rigorous research,Lifecycle Investingpresents a simple but radical idea that will shake up how we think about retirement investing even as it provides a healthier nest egg in a nicely feathered nest.

Developments in methodologies, agglomeration, and a range of applied issues have characterized recent advances in regional and urban studies. Volume 5 concentrates on these developments while treating traditional subjects such as housing, the costs and benefits of cities, and policy issues beyond regional inequalities. Contributors make a habit of combining theory and empirics in each chapter, guiding research amid a trend in applied economics towards structural and quasi-experimental approaches. Clearly distinguished from the New Economic Geography covered by Volume 4, these articles feature an international approach that positions recent advances within the discipline of economics and society at large. Editors are recognized as leaders and can attract an international list of contributors Regional and urban studies interest economists in many subdisciplines, such as labor, development, and public economics Table of contents combines theoretical and applied subjects, ensuring broad appeal to readers

The central role of the housing market in the recent recession raised a series of questions about similar episodes throughout economic history. Were the underlying causes of housing and mortgage crises the same in earlier episodes? Has the onset and spread of crises changed over time? How have previous policy interventions either damaged or improved long-run market performance and stability? This volume begins to answer these questions, providing a much-needed context for understanding recent events by examining how historical housing and mortgage markets worked—and how they sometimes failed. Renowned economic historians Eugene N. White, Kenneth Snowden, and Price Fishback survey the foundational research on housing crises, comparing that of the 1930s to that of the early 2000s in order to authoritatively identify what contributed to each crisis. Later chapters explore notable historical experiences with mortgage securitization and the role that federal policy played in the surge in home ownership between 1940 and 1960. By providing a broad historical overview of housing and mortgage markets, the volume offers valuable new insights to inform future policy debates.
