| Spring 2004 | How
much does bank capital matter? 
(99k)(by David Aikman and Gertjan Vlieghe of the Bank's Monetary Assessment and Strategy Division). In this article we consider how the composition of banks' balance sheets between capital and deposits affects the transmission of economic shocks. We use a small, stylised model of the economy to analyse under which conditions firms are unable to borrow as much as they would like from banks, and banks are unable to attract as many deposits as they would like from households. We show that, following shocks to aggregate productivity and bank net worth, the response of output in this model economy with credit constraints is both larger and longer-lasting than in a similar economy where credit constraints do not bind. This is because an adverse shock lowers bank capital, which constrains lending to firms and amplifies the fall in output; and it takes time for banks to rebuild their capital so it takes time for output to return to its initial level. We find that, in our model, only a small proportion of the fluctuations of output in response to productivity shocks is due to the bank capital channel, but this channel is more important when there are direct shocks to bank capital. Measuring total factor productivity for the United Kingdom
(99k)(by Charlotta Groth, Maria Gutierrez-Domenech and Sylaja Srinivasan of the Bank's Structural Economic Analysis Division). A good understanding of productivity growth is important for understanding aggregate supply capacity, and so for the conduct of monetary policy. To understand the sources of supply capacity well, it is important to measure output and factor inputs correctly. This article summarises recent and ongoing research at the Bank of England on improved measures of factor inputs. This work explicitly accounts for changes in the quality of these inputs and for the flow of services available from them, as well as for the costs of adjusting the level and utilisation of the inputs over time. This research was presented at a workshop on 'measuring factor inputs' held at the Bank of England in December 2003. |
| Winter 2003 | The
macroeconomic impact of revitalising the Japanese banking
sector
(185k) (by Katie Farrant and Bojan Markovic of the Bank's International Economic Analysis Division and Gabriel Sterne of the Bank's Monetary Assessment and Strategy Division). In this article we assess the possible macroeconomic effects of proposals to revitalise the banking system in Japan. Our analysis is supported by a theoretical model that incorporates various interactions between the banking sector and the wider economy. In the long run, a planned reduction in the ratio of non-performing loans (NPLs) to total loans and the intended fall in the risk premium faced by Japanese banks may help to boost the level of investment. Achieving a revitalised banking system cannot be done costlessly, however, and our model suggests that there may be some negative short-run macroeconomic impact as credit growth is reduced. |
| Winter 2002 | The
external balance sheet of the United Kingdom: recent developments
(98k) (by Robert Westwood of the Bank's Monetary and Financial Statistics Division and John Young of the Bank's Domestic Finance Division). The external balance sheet (or international investment position) gives the most complete picture of the stock position of a country in its financial transactions with the rest of the world. The very breadth of coverage of the data leads inevitably to problems of measurement and valuation. Nevertheless, subject to certain qualifications, the data can throw some light on macroeconomic and financial stability issues related to the United Kingdom's cross-border financial links. This article, one in an annual series, discusses the recent evolution of the United Kingdom's external balance sheet, reviewing along the way some of the main methodological issues that impinge on an interpretation of the data. It concludes that, despite a persistent current account deficit, the balance of probability is that the United Kingdom still has net external assets, or at least the capacity to generate net investment income from overseas. There are also some grounds for optimism that the structure of its assets and liabilities has left the United Kingdom in a fairly strong position to withstand financial shocks. |
