The general accounting framework for... the capital account... Rows represent assets or debts. ...Columns represent sectors of the economy ...Entries in cells ...can be postive, negative, or zero. A negative entry means... the sector... is a debtor in the... asset indicated by the row. ...The sum across the row is the net exogenous supply of the asset to the economy ...For stocks of goods, this ...is the economy's inheritance from the past. For internally generated financial assets the net... supply... is zero. If from the sums in the final column the... government's holdings of an asset are subtracted (or its debt added), the net holdings of the private economy result. The sum of a column represents the net worth of a sector. The sum of the final column is the national wealth. ...[P]rivate wealth differs from this total by the amount of the government's net worth. If government is a net debtor... if its stocks of goods are ignored, then private wealth exceeds national wealth.

I shall argue that Keynesian macroeconomics neither asserts nor requires nominal wage and/or price rigidity. It does assert and require that markets not be instantaneously and continuously cleared by prices.

I probably always say the same things; I hope people don't remember. One of the same things I say is that Japanese macroeconomic policy is perversely and inexcusably incompetent, and I surely would say that again. It's true-as Paul Krugman, a fellow participant in this program, has been saying and as I have said here in previous years-that Japan has reinvented the Keynesian liquidity trap. It can now reappear in classrooms where it had been long ignored or at best barely mentioned as a curiosum of the Great Depression.
