oil-exporting economies largely dependent on oil revenues and oil income fluctuation are one of the most important factors that influence sectors of the economy specially the stock market. this paper investigate the relationship between oil markets and stock return volatility and transmission in a selection of opec countries, using a multivariate garch models (full-vech) over the period may 201...

Recent studies of purchasing power parity (PPP) account for the possible presence of unit roots in nominal exchange rates and relative price indices by applying standard unit-root tests to real exchange rates, which are ratios of nominal exchange rates and relative price indices. These studies occasionally find evidence of PPP, but as a whole, the evidence is not definitive. Standard unit-root ...

We develop a theory of money and credit as competing payment instruments, then put it to work in applications. Buyers can use cash or credit, with the former (latter) subject to the inflation tax (transaction costs). Frictions making the choice of payment method interesting also imply equilibrium price dispersion, and together these deliver closed-form solutions for money demand. The model can ...

In this paper we consider the dynamics of spot and futures prices in the presence of arbitrage. We propose a partially linear error correction model where the adjustment coefficient is allowed to depend non-linearly on the lagged price difference. We estimate our model using data on the DAX index and the DAX futures contract. We find that the adjustment is indeed nonlinear. The linear alternati...

Before the introduction of a call auction at the close, the last minute of trading at the Paris Bourse was the most active of the whole day. Even though the bid–ask spread increased substantially, the probability of large and aggressive orders increased, as did price volatility. In addition, both the one-minute returns and the proportion of partially hidden orders increased. In this paper, we d...

This paper investigates how and to what extent institutional development influences and permits firm-specific information to be incorporated into share prices, as measured by stock price synchronicity. Tracing the experience of China, an economy undergoing dramatic changes in the last 20 years with rich variation in experiences across provinces, this paper reveals that stock price synchronicity...

I study affiliated, pure common-value auctions with ex-ante asymmetric buyers. For the two-buyer case I characterize and prove uniqueness of the equilibrium of hybrid auctions where the payment is a weighted average of the highest and second-highest bids. A recursive method to explicitly compute the equilibrium is presented. It is shown that any hybrid auction yields at least as much revenue as...

We predict and find that accounting restatements induce economically meaningful share price declines among non-restatement firms in the same industry. These price declines are most pronounced among non-restatement firms with low accounting quality, as measured by industry adjusted accruals. Our results are consistent with the notion that accounting restatements cause investors to reassess the c...

We use a state-dependent model where pricing rules are optimal to examine the costs of a money-based disinflation under various assumptions about the credibility of the policy change. Our analysis allows us to relate actual credibility and future inflation inertia to the asymmetry of the price deviation distribution. An important implication of our statedependent setting is that disinflation ca...

We study the case where parallel trade (PT) stems from government price controls in a foreign country. We remove the presumption that PT blunts dynamic efficiency if the government has partial commitment ability. We model the R&D firm’s option to serve the foreign country, and find that PT may improve quality, depending on preferences for quality. Improving quality may be a sufficient condition...
