(a) Kalecki distribution (10 marks)

According to Michal Kalecki (Theory of Economic Dynamics, 1954), the functional distribution of income is determined by the interaction of the degree of monopoly and the level of investment. The degree of monopoly, measured by the mark-up factor m (the ratio of price to average prime cost), fixes the wage-profit share. Using the pricing equation p = m(u + w), the relative wage share is expressed as W/Y = 1/[1 + (m - 1)(1 + j)], where j is the materials-to-wages ratio. Thus, a higher mark-up implies a lower wage share.

Simultaneously, the level of investment determines the absolute mass of profits. Under the classical savings assumption that workers do not save, total profits equal investment plus capitalists' consumption (P = I + Cₖ). These two determinants interact to determine the level of output: while investment fixes the total mass of profits, the degree of monopoly determines how that mass is divided. Consequently, a higher mark-up requires a lower equilibrium level of income and employment to deliver the same profit mass. This framework rejects marginal productivity theory, emphasizing instead the role of industrial composition and the mark-up in the wage-profit division.

(b) Classical AD (10 marks)

In the classical system, the aggregate demand (AD) curve is derived from the quantity theory of money. Using the equation of exchange MV = PY (Irving Fisher) or the Cambridge equation M = kPY, where M is the money supply, V is the velocity of circulation, and P is the price level, the classical AD function is expressed as Y = MV/P. This relationship implies that the real value of output is determined by the real value of the fixed nominal money stock.

The special property of this curve is that it is a rectangular hyperbola with unit elasticity. It is downward sloping (dY/dP = -MV/P² < 0) because an increase in the price level reduces the real value of money, thereby reducing the quantity of goods demanded. The curve shifts only with changes in M or V. In the classical model, the aggregate supply curve is vertical at full-employment output, reflecting the classical dichotomy and the neutrality of money. Thus, changes in the money supply affect only the price level, leaving real output unchanged.

(c) Term structure (10 marks)

The term structure of interest rates, or the yield curve, describes the relationship between interest rates and the maturity of bonds. The arbitrage rule inherent in this structure is the pure expectations theory (Fisher, Lutz), which states that a long-term rate equals the geometric average of expected future short-term rates. The condition is (1 + Rₙ)ⁿ = Π(1 + E rₜ), where Rₙ is the long rate and E rₜ are expected future spot rates. This implies that the forward rate is the expected future spot rate, as riskless profits from rolling over short-term bonds versus holding to maturity are competed away by arbitrage.

However, the pure expectations theory does not explain the normally upward slope of the yield curve. Modifying theories include Hicks's liquidity premium theory, which adds a positive term premium for holding long-term bonds; Culbertson's market segmentation theory, which argues that different maturities are separate markets; and Modigliani-Sutch's preferred habitat theory, which suggests investors have preferred maturities but will shift if the return is sufficiently higher. These theories explain the shape of the curve and the role of risk premia.

(d) Public vs private; free rider (10 marks)

Public and private goods are distinguished by the criteria of rivalry and excludability. Private goods are rival and excludable, where the optimality condition is MRS = MRT and demand curves are summed horizontally. In contrast, public goods (Samuelson, 1954) are non-rival and non-excludable. The Samuelson condition for public goods is Σ MRS = MRT, and demand curves are summed vertically. This distinction is crucial for determining the efficient level of provision.

The 'Free Rider' problem arises because individuals can benefit from public goods without paying for them. This leads to a failure of voluntary preference revelation, as individuals have an incentive to understate their willingness to pay. The consequence is the under-provision of public goods, a significant market failure. Lindahl pricing, in which each person pays a tax-price equal to his marginal benefit, would be efficient but cannot be reached voluntarily for the same reason. While club goods (Buchanan) and common-pool resources sit in between these categories, the free-rider problem necessitates tax finance or demand-revealing mechanisms like the Clarke-Groves mechanism to achieve an efficient outcome.

(e) Crowding-out and foreign capital (10 marks)

The crowding-out effect in fiscal policy refers to the displacement of private investment by government borrowing. When the government increases spending, it raises the demand for loanable funds, which increases the interest rate. Costlier borrowing then reduces private investment. The magnitude of this effect depends on the slope of the LM curve: it is complete when the LM curve is vertical (at full employment) and zero in a liquidity trap. Under Ricardian equivalence (Barro, 1974), debt-financed spending is offset by higher private saving, neutralising the stimulus itself.

Foreign capital inflows (FDI, FPI, external commercial borrowings) can mitigate this effect by augmenting the supply of loanable funds. Under the Mundell-Fleming model, with perfect capital mobility and a fixed exchange rate, fiscal policy is fully effective because capital inflows finance the deficit, preventing the interest rate from rising. This relaxes the savings and foreign-exchange constraints (Chenery-Strout two-gap logic). However, under flexible exchange rates, the inflow may lead to currency appreciation, which can crowd out net exports. Where the deficit finances public infrastructure, higher private returns can even 'crowd in' investment. Thus, foreign capital helps to mute the interest-rate channel of crowding-out.
