In this paper we provide an empirical analysis of the announcement and implementation of rights issues and stock dividends in the thinly traded Istanbul Stock Exchange. The efficiency of the Turkish market with respect to this information set is tested at different time horizons characterized by different development levels of the market. Evidence is detected of different price reactions for the different development phases of the market as well as for the board meeting and actual implementation information. As the market matures, neither the board meeting nor the actual implementation of stock dividends-rights offerings cause significant price reactions. Besides the traditional event study methodology, non-parametric tests such as sign and rank tests are also employed but are found to be unsuitable for this particular case.

We present a continuum economy with risk neutral agents having heterogeneous expectations and restricted short sales. A stochastic version of the model is also formulated and the resulting time series behavior of the price and volume series under a specific money supply process derived. The implications of the model are tested in the emerging Turkish stock market where institutional arrangements comply with the restrictions of the model. The results indicate that, as predicted by the model, price levels and trading volume are cointegrated. The error correction models are also estimated and found to be significant in most cases

This paper investigates calendar anomalies in the Turkish foreign exchange markets during 1986-1994 period. Changes in the free market and official daily exchange rates between the Turkish lira (TL) and US dollar (USD) and the German mark (DM) are examined for empirical regularities on different days of the week, around the turn of the month and before holidays. The findings reveal that free market rates exhibit day-of-the-week and week-of-month effects. In addition free market DM returns display a holiday anomaly. These calendar anomalies are explained by cash disbursement patterns, together with currency substitution in the economy. The impact of treasury auctions and banks' management of liquidity on day-ofthe-week effect is also discussed.
