Many people are concerned about the budget deficit of the U.S. federal government. Suggest at least three possible negative economic effects of a budget deficit and three possible economic benefits of a budget deficit.
As traders, investors, and creditors become increasingly concerned that the government would resort to high inflation to reduce the real value of government debt or that a fiscal deadlock with unpredictable consequences would arise, investor confidence may be severely undermined;The fiscal and current account imbalances may also cause a loss of confidence among participants in foreign exchange markets and in international credit markets, as participants in those markets become alarmed not only by the ongoing budget deficits but also by related large current account deficits;The loss of investor and creditor confidence, both at home and abroad, may cause investors and creditors to reallocate funds away from dollar-based investments, causing a depreciation of the exchange rate, and to demand sharply higher interest rates on U.S. government debt;The increase of interest rates, depreciation of the exchange rate, and decline in confidence can reduce stock prices and household wealth, raise the costs of financing to business, and reduce private-sector domestic spending;The disruptions to financial markets may impede the intermediation between lenders and borrowers that is vital to modern economies, as long-maturity credit markets witness potentially substantial increases in interest rates and become relatively illiquid, and the reduction in asset prices adversely affects the balance sheets of banks and other financial intermediaries;The inability of the federal government to restore fiscal balance may directly reduce business and consumer confidence, as the view of the ongoing deficits as a symbol of the nation's inability to address its economic problems permeates society, and the reduction in confidence can discourage investment and real economic activity;These various effects can feed on each other to create a mutually reinforcing cycle; for example, increased interest rates and diminished economic activity may further worsen the fiscal imbalance, which can then cause a further loss of confidence and potentially spark another round of negative feedback effects.Although it is impossible to know at what point market expectations about the nation's large projected fiscal imbalance could trigger these types of dynamics, the harmful impacts on the economy, once these effects were in motion, would substantially magnify the costs associated with any given underlying budget deficit and depress economic activity much more than the conventional analysis would suggest. Indeed, the potential costs and fallout from such fiscal and financial disarray provide perhaps the strongest motivation for avoiding substantial, ongoing budget deficits. budget deficit can have positive macroeconomic effects in the long run if it is used to finance extra capital spending that leads to an increase in the stock of national assets. For example, higher spending on the transport infrastructure improves the supply-side capacity of the economy promoting long-run growth. And increased public-sector investment in health and education can bring positive effects on labour productivity and employment. The social benefits of increased capital spending can be estimated through use of cost-benefit analysis.

BC.

Compare and contrast the impact of a faster rate of population growth on the standard of living (output per worker) in the models by Solow, Malthus, and Kremer.
Solow: increased population decreases standard of living because there is a smaller output per worker Malthus: Resources are consumed at a faster rate than they can be produced, which lowers the amount per worker Kremer: Larger population equates to a larger pool of people to generate new ideas. Technological progress accelerates.
A given increase in taxes shifts the IS curve more to the left the:
larger the marginal propensity to consume.
