The majority of the poor lack access to bank accounts and have to use costly informal savings mechanisms. Using a field experiment, I randomly gave access to simple bank accounts with no fees at local bank branches to a large sample of female household heads in Nepal. Results show that there is untapped demand for savings accounts and that the poor do save. Access to the savings accounts increa...

We analyse the incentive impact of bank capital regulation in a model with endogenous capital, assuming regulators randomly audit banks and require undercapitalised banks either to bear the fixed cost of new issue or to liquidate. Forward looking banks with sufficient franchise value maintain a buffer of capital in excess of the regulatory minimum. In our dynamic setting we show, amongst other ...

The purpose of this paper is to make a comparative analysis of modern gross payment systems, emphasizing on the implications of the availability of intraday liquidity and the different mechanisms used to provide this liquidity. The possibility of default and the risk of the intraday credit are first introduced to determine the implications of its existence on banks’ behaviour and on the probabi...

We study experimental coordination games to examine through which transmission channels, and under which information conditions, a panic-based depositor-run at one bank may trigger a panic-based depositor-run at another bank. We find that withdrawals at one bank trigger withdrawals at another bank by increasing players’ beliefs that other depositors in their own bank will withdraw, making them ...

Insider trading problems relating to Japanese seasoned equity offerings (SEO) have attracted the attention of many investors. The purpose of this paper is to examine SEO insider problem and to provide suggestions to solve the problem. We have several findings. First, all four of the SEO insider firms experienced negative abnormal stock returns and high trading volume just two weeks before SEO a...

We build a simple model of banking in the presence of macroeconomic shocks where the comparative roles of private and public monitors can be analyzed. This model provides endogenous justifications for prudential regulation (capital requirements) and emergency liquidity assistance by the Central Bank (lender of last resort). We show that market discipline can be helpful, but does not solve the f...

This paper explores the role of diversification and size in protecting information. We present a simple two period credit market with a sophisticated lender faced with competitors who free ride on his screening activity. Absent commitment problems, the lender funds one borrower and exerts optimal evaluation. When borrowers cannot commit to a long term relationship, the free riding problem is re...

We provide a model of the impact of bank mergers on loan competition, individual reserve management and aggregate liquidity risk. Banks hold reserves against liquidity shocks, refinance in the interbank market and compete in a differentiated loan market. A merger creates an internal money market that induces financial cost advantages and may increase reserve holdings. We assess the liquidity ri...

This paper argues that the existence of bank networks is important for banks ́ reaction to monetary policy. For the example of Germany, the VAR analysis shows that following a monetary contraction small banks access the interbank market indirectly through the head institutions of their respective network organisations. The interbank flows within these networks allow small banks to access funds t...

In this paper we estimate a time-series model of excess liquidity in the Egyptian banking sector. While financial liberalization and financial stability are found to have reduced excess liquidity, these effects have been offset by an increase in the number of violent political incidents arising from conflict between radical Islamic groups and the Egyptian state. The link between political event...
