We examine the match/mismatch between demand and supply of impact investments. show that some geographic regions display an upward match, while others exhibit a downward match. explain how with well-developed (or less-developed) economies are not necessarily equal to investment markets. also highlight sectors exhibiting match or mismatch investments, potential reasons. Regarding both sector con...

Using non-parametric weak separability tests that are extended to allow for measurement errors in the data, a broad group of UK monetary assets is found to be weakly separable from consumer goods and leisure over the larger part of the nineties. Financial innovations have made assets with substantial interest rate risk (e.g. unit trusts) more liquid and recent developments in monetary aggregati...

Consumers make transactions of different sizes over time. This paper shows that this fact, together with transaction costs of various assets, can help in developing a theory of liquidity. Assets with different cost structures are used to purchase different sizes of transactions. This can explain the demand for money itself, the precautionary demand for money, and the demand for cash and demand ...

This paper examines some of the characteristics of the foreign exchange market in the 1920s floating period.

In order to deal with the extreme kurtosis in the exch...

This paper draws attention to the limitations of the standard unit root/cointegration approach to economic and financial modelling, and to some of the alternatives based on the idea of fractional integration, long memory models, and the random field regression approach to nonlinearity. Following brief explanations of fractional integration and random field regression, and the methods of applyin...

The immune system can be efficiently stimulated and targeted to specific antigens expressed exclusively or preferentially by experimental cancers. The foremost limitations to extending this vaccine technology to the prevalent epithelial-derived cancers are the lack of: (a) identified tumor-associated antigens recognized by cellular immunity; (b) antigens expressed on the majority of tumor cells...
