Using the daily data of Chinese 7-day repo rates from January 1, 1997 to December 31, 2008, this paper tests a variety of popular spot rate models, including single-factor diffusion, GARCH, Markov regime-switching and jump-diffusion models.

We explore buyback contracts in a supplier-retailer supply chain where the retailer faces a price-dependent downward-sloping demand curve subject to uncertainty. We formulate the problem as a supplier-led Stackelberg game and derive explicitly the equilibrium contract parameters along with the...

Modelling and forecasting symbolic data, especially interval-valued time series (ITS) data, has received considerable attention in statistics and related fields. The core of available methods on ITS analysis is based on various applications of conventional linear modelling. However, few works...

Natural disasters can cause heavy economic losses to firms that may propel them to overuse earnings management to change public perceptions about the damage brought by these events. This may lead to potential profit manipulation and accounting fraud, eventually damaging the interests of...

There are still many uncertainties regarding the possible influences of global climate change in the mid-latitude regions, owing to rather limited research and lack of empirical evidence. This paper systematically evaluates the economic impacts of climate variation by constructing a 27-year...
