Abstract In this paper we investigate global determinants of oil price volatility by employing a time-varying parameter vector autoregressive (TVP-VAR) model. We focus on realised and consider the impact from set potential including supply, demand, inventory, financial market uncertainty, interbank stress, as well as, trends in different currencies. these factors utilising monthly data over per...

This paper examines the price volatility in the silver spot (cash) market. A host of Generalized Autoregressive Conditional Heteroskedasticity (GARCH) models are used to analyze and gain a better understanding of the volatility of silver prices. We find the TGARCH (1,1) model indicates that both positive and negative shocks do not have a significant effect on volatility in the silver spot marke...

We derive representations for the stock price drift and volatility in the equilibrium of agents with arbitrary, heterogeneous utility functions and with the aggregate dividend following an arbitrary Markov diffusion. We introduce a new, intrinsic characteristic of the aggregate dividend process that we call the ”rate of discounting volatility” and show that, in equilibrium, the size of market p...

Volatility characterizes the amplitude of price return fluctuations. It is a central magnitude in finance closely related to the risk of holding a certain asset. Despite its popularity on trading floors, volatility is unobservable and only the price is known. Diffusion theory has many common points with the research on volatility, the key of the analogy being that volatility is a time-dependent...

We present results from laboratory emissions markets designed to investigate the effects of price controls and permit banking on limiting permit price risk. While both instruments reduce between-period price volatility and within-period price dispersion, combining price controls and permit banking yields important benefits. Banking alone produces high permit prices in earlier periods that fall ...

E nergy analysts sometimes speak of oil’s “golden era,” that 100-year stretch between 1874 and 1974 when the real price was relatively stable within a range from $10 to $20 per barrel (BP, 2008) in 2007 dollars. Figure 1 shows that in recent decades, that stability has ended. In October 1973, several Arabic members of the Organization of the Petroleum Exporting Countries (OPEC) announced that i...
