Quantum prediction GJR model and its applications

In this paper, a new statistical method to deal with the quantum finance is proposed. Through analyzing the stock data of China Mobile Communication Corporation, we discover its quantum financial effect, and then we innovate the method of testing the existence of the quantum financial effect. Furthermore, the classical normal process of the Glosten–Jagannathan–Runkle (GJR) model has been changed into the quantum wave‐function distribution, which is based on the ‘one‐dimensional infinitely deep square potential well’. The research shows that the quantum GJR model can reveal the interior uncertainty of the financial market and has a better prediction availability.

Accounting for Sustainable Development over the Long‐Run: Lessons from Germany

We construct long‐run sustainability indicators based on changes in Comprehensive Wealth – which we refer to as Genuine Savings (GS) – for Germany over the period 1850–2000. We find that German sustainability indicators are positive for the most part, although they are negative during and after the two World Wars and also the Great Depression. We also test the relationship between these wealth changes and a number of measures of well‐being over the long‐run: changes in consumption as well as changes in average height and infant mortality rates. We find a positive relationship between GS and our well‐being indicators over different time horizons, however, the relationship breaks down during WWII. We also test if the GS/Comprehensive Wealth framework is able to cope with massive disinvestment at the end of the Second World War due to war‐related destructions and dismantlement. We find that negative rates of GS were by and large avoided due to the accumulation of technology and growth‐friendly institutions. We demonstrate the importance of broader measures of capital, including measures of technological progress, and its role in the process of economic development; and the limits of conventional measures of investment to understand why future German consumption did not collapse.     

SOCIAL COMPARISON AND SUBJECTIVE WELL‐BEING: DOES THE HEALTH OF OTHERS MATTER?

The importance of social comparison in shaping individual utility has been widely documented by subjective well‐being literature. So far, income and unemployment have been the main dimensions considered in social comparison. This paper aims to investigate whether subjective well‐being is influenced by inter‐personal comparison with respect to health. Thus, we study the effects of the health of others and relative health hypotheses on two measures of subjective well‐being: happiness and subjective health. Using data from the Italian Health Conditions survey, we show that a high incidence of chronic conditions and disability among reference groups negatively affects both happiness and subjective health. Such effects are stronger among people in the same condition. These results, robust to different econometric specifications and estimation techniques, suggest the presence of some sympathy in individual preferences with respect to health and reveal that other people's health status serves as a benchmark to assess one's own health condition.
