This note derives an approximate solution to a continuous-time intertemporal portfolio and consumption choice problem. The problem is the continuous-time equivalent of the discrete-time problem studied by Campbell and Viceira (1999), in which the expected excess return on a risky asset follows an AR(1) process, while the riskless interest rate is constant.The note also shows how to obtain continuous-time parameters that are consistent with discrete-time econometric estimates. The continuous-time solution is numerically close to that of Campbell and Viceira and has the property that conservative long-term investors have a large positive intertemporal hedging demand for stocks.JEL classification: G12.

This paper analyses the relationship between air pollution and tourism demand in Beijing. The study method is based on a gravity model, in which air quality variables are incorporated into the model of tourism demand. The results obtained show that air pollution has a negative influence on tourism flows and that this effect is more pronounced for inbound than for domestic tourism. The findings also show that a simple index such as the classification of good and bad air‐quality days is a good representation of the air pollution factors taken into account by tourists in their travel decision.

This article explores the spending patterns of tourists by market segments of expenditure distribution. We focus on the case of the Canary Islands, that is, a region that is one of the main destinations in the European tourism market, and distinguish between expenditure at origin and expenditure at destination. To do this, we use unconditional quantile regression (QR), which is more appropriate than conditional QR for the interpretation of coefficients. The results suggest that spending behaviour is heterogeneous among quantiles of expenditure in terms of income, price, level of loyalty and hotel accommodation effects. Furthermore, some differences arise between the pattern of expenditure at origin and the one at destination, and among items of expenditure at destination.

We find empirical evidence suggesting that the volatility dynamics of Japanese firms cross-listed in the US is characterized as a Meteor Shower with Country-Specific News. Furthermore, we find differences in volatility dynamics depending on the international exposure of firms. These differences are consistent with a higher contribution of foreign traders (foreign markets) to the price discovery process of Japanese firms with higher international exposure, and with a news-correlated process for these firms. We also find weaker empirical evidence suggesting a higher contribution of Japanese traders to the price discovery process of Japanese firms with lower international exposure.
