Equity Premium with Habits, Wealth Inequality and Background Risk

In an exchange economy with endowment inequality, we investigate how preferences with external habits affect the equity risk premium. We show that the dynamics of external additive habits with wealth inequality are complex when a background risk is present. It is ambiguous whether wealth inequality will increase or decrease the equity premium even when the income uncertainty is low. This result extends literature by suggesting that wealth inequality has a small role in explaining asset pricing puzzles.

The Equity Risk Premium Puzzle in Pakistan

Our study uses the consumption-based asset-pricing power utility model to test theEquity Risk Premium (ERP) puzzle in Pakistan. The study has collected monthly stock pricedata from July 1997 to December 2017 from the PSX data portal. We extracted informationabout macroeconomic factors such as inflation and risk-free interest rate from the State Bankof Pakistan. Moreover, the study used private consumption and population data from thePakistan Bureau of Statistics. The results suggest that the ERP puzzle has a strong occurrencein Pakistan, a phenomenon previously associated with only developed markets. Onedisadvantage of the present investigation is the small sample size. A longer time durationcould have reduced short-term biases. Past researchers have suggested different approachesfor solving the equity premium puzzle. For instance, some studies used improvised structuralmodels to justify the equity risk premium puzzle using macroeconomic factors.

Before the cult of equity: the British stock market, 1829–1929

We analyze the development and performance of the British equity market during the era when it reigned supreme as the largest in the world. Using an extensive monthly dataset of thousands of companies, we identify the major peaks and troughs in the market and find a relationship with the timing of economic cycles. We also show that the equity risk premium was modest and, contrary to previous research, domestic and foreign stocks earned similar returns for much of the period. We also document the early dominance of the transport and finance sectors and the subsequent emergence of many new industries.

Determinants of the implied equity risk premium in Brazil

<p>This paper proposes and tests market determinants of the equity risk premium (ERP) in Brazil. We use implied ERP, based on the Elton (1999) critique. We demonstrate that the calculation of implied, as opposed to historical ERP makes sense, because it varies, in the expected direction, with changes in fundamental market indicators. The ERP for Brazil is calculated as a mean of large samples of individual stock prices in each month in the January, 1995 to September, 2015 period, using the “implied risk premium” approach. As determinants of changes in the ERP we obtain, as significant, and in the expected direction: changes in CDI rate, country debt risk spread, US market liquidity premium and level of the S&amp;P500. The influence of the proposed determining factors is tested with the use of time series regression analysis. The possibility of a change in that relationship with the 2008 crisis was also tested, and the results indicate that the global financial crisis had no significant impact on the nature of the relationship between the ERP and its determining factors. For comparison purposes, we also consider the same variables as determinants of the ERP calculated with average historical returns, as is common in professional practice. First, the constructed series does not exhibit any relationship to known market events. Second, the variables found to be significantly associated with historical ERP do not exhibit any intuitive relationship with compensation for market risk.</p>
