HSC Economics: what actually gets examined

Better responses

• Treated trade as two-way, showing how imports raise a country's productive capacity or living standards and how exports lift workers out of poverty, while noting costs such as environmental damage from export-led growth.
• Grounded the reasons for trade in comparative advantage, wider product choice and economies of scale, then followed lower global protection through to its uneven effect on incomes in developing and advanced economies.
• Built a case study around a range of globalisation impacts on both growth and development in the chosen economy, with comparative statistics behind each judgement.
• Explained how and why each driver of international integration worked, tying it to trends in trade and financial flows, gross world product and the roles of the WTO, IMF, World Bank and G20.
• Handled development as a qualitative idea spanning health, education and literacy as well as output, and could set out the limits of income alone as a gauge of quality of life.

Where marks were lost — and how to keep them

• Separating the causes of gaps in growth and development between nations from the consequences of growth and development, and keeping the answer on the reasons asked for.
• Telling a regional business cycle apart from a single domestic cycle, and an emerging economy apart from a developing one, before comparing them.
• Following a quota increase step by step: more supply, lower prices, a more competitive market, then efficiency gains for some domestic firms and closures and job losses for others.
• Recognising that development can improve environmental outcomes over the longer run through awareness and international cooperation, rather than presenting only the traditional trade-off.
• Analysing rather than describing each method of protection, drawing out its implications for Australian firms and government specifically and citing evidence on protection rather than on free trade.

Better responses

• Explained currency value through demand and supply under a float: a higher cash rate lifts market interest rates, attracts foreign capital and so raises demand for the Australian dollar.
• Worked through more than two balance of payments components in turn, showing how each one moves the value of the dollar, with the stimulus and own knowledge used together.
• Set out how a current account deficit is mirrored by a surplus on the capital and financial side, and how past capital inflow feeds back into the net primary income deficit.
• Linked shifts in what Australia trades, how much and with whom to its economic performance, instead of explaining what had driven those shifts in composition and direction.
• Drew out an appreciation's positive and negative effects for individuals, firms and government over both time frames, bringing in theory like Dutch disease and the reverse J-curve.

Where marks were lost — and how to keep them

• Keeping causation pointed the right way: the task was how balance of payments items move the dollar, not how the dollar moves those items.
• Distinguishing the Trade Weighted Index from the mechanism that sets the exchange rate, and direct intervention such as dirtying the float from indirect intervention through interest rates.
• Separating global causes of a currency movement from domestic ones, reading a diagram as a depreciation driven by falling demand, and not confusing appreciation effects with depreciation effects.
• Sustaining the chain through more than one component: several balance of payments items acting on the dollar, or a protectionist measure hitting exports, imports and net primary income alike.
• Covering every element of the balance of payments rather than only the current account, and keeping a trend distinct from the cyclical and structural reasons behind it.

Better responses

• Compared how high and low inflation, short run and long run, affect individuals, firms and government, and chained a wage rise through spending to demand-pull inflation and weaker export competitiveness.
• Defined full employment through the NAIRU, matched cyclical unemployment to short-run macroeconomic policy and structural unemployment to long-run microeconomic policy, and drew labelled Phillips curves.
• Redrew a Lorenz curve toward the line of equality, then tied the dimensions and trends of inequality to its primary and secondary effects and to both economic and social costs, backed by statistics.
• Set out the implications of pursuing environmental sustainability across growth, inflation, unemployment, inequality and external stability, separating short-run from long-run effects.
• Explained sustainable growth by linking macroeconomic policy to aggregate demand and microeconomic policy to aggregate supply and output, while acknowledging conflicting goals and policy limits.

Where marks were lost — and how to keep them

• Separating a positive externality from the reduction of a negative one, and private benefit from social benefit, with public goods defined by non-rivalry and non-excludability.
• Distinguishing the unemployment rate from the participation rate, and policies that shift the NAIRU from those that lower cyclical unemployment, with the given data read against the NAIRU.
• Answering the effects question that was set: causes of inflation were not needed in an effects response, and a question on the dimensions of inequality is not one on its causes or policy remedies.
• Explaining full employment as a process running from income to consumption, production and labour demand, rather than as a simple fall in the unemployment rate.
• Naming environmental issues specific to Australia rather than global generalities, using terms such as structural unemployment and cost inflation, and explaining the theory behind any diagram used.

Better responses

• Covered both sides of the budget, taxation revenue and outlays on infrastructure and welfare, tied them to the counter-cyclical stance, and named a way of financing a deficit together with its consequence.
• Stated the purpose of monetary policy through price stability, full employment and stabilising activity, kept that separate from the cash-rate mechanism, and traced at least two effects of a rate cut.
• Judged monetary and fiscal policy separately on growth and price stability, with each verdict supported by Australian data and integrated theory rather than assertion.
• Explained why objectives conflict, pointing to resource constraints or aggregate demand pressure, supported by a Phillips curve or PPC and a specific RBA or budget decision that prioritised one goal.
• Linked training and employment programs to lower structural unemployment, distinguished the wage determination systems, and judged microeconomic policy across types of unemployment and time frames.

Where marks were lost — and how to keep them

• Defining fiscal policy in proper terms and weighing both the short-run and long-run consequences of a deficit financing method, not just its immediate effect.
• Keeping the cash rate tied to interest rates and the money supply rather than the dollar, so that holding the cash rate is not confused with managing the exchange rate.
• Separating macroeconomic from microeconomic policy, and making an actual judgement of effectiveness instead of only describing how a policy relates to unemployment.
• Identifying and defining each objective in a conflict, then showing causation behind the trade-off rather than simply asserting that one exists.
• Distinguishing a market-based environmental policy, which works through price and quantity, from regulations and restrictions when a question specifies the former.
