The Ups and Downs of New Zealand House Prices

This paper identifies the expansion and contraction phases of New Zealand's national and regional house prices, by employing techniques typically used to study cycles in real activity, the so-called Classical cycle dating method. We then enquire into the nature of the cycles, addressing five questions: (1) What are the New Zealand and regional house price cycles, and do the regional cycles differ from the national cycle?; (2) What are the typical durations, magnitudes and shapes of these house price cycles?; (3) Do cycles in house prices match cycles in economic activity, at either national or regional levels?; (4) Does it matter which of the two main sets of house price series are used? i.e. Quotable Value New Zealand (QVNZ) or Real Estate Institute of New Zealand (REINZ)?; and (5) Does the sample period matter? Findings are evaluated in the context of work by Grimes, Aitken and Kerr (2004), and Hall and McDermott (2005). Avenues for further research are suggested.House price cycles; regional business cycles; classical business cycle; New Zealand

APPLICATION OF A DYNAMIC PANEL DATA ESTIMATOR TO CROSS-COUNTRY COFFEE DEMAND: A TALE OF TWO ERAS

We estimate price and income elasticities of demand for green coffee beans in panels of up to 40 countries, both during and after the operation of export quotas under International Coffee Agreements. The dynamic panel estimator proposed in Han and Phillips (2007) is used because it is a consistent estimator, for any length of panel, regardless of the presence of unit roots. Dynamic panel data models, of any type, do not seem to have been previously applied to coffee demand. We find evidence of a concave relationship between income and coffee consumption for countries which are members of the International Coffee Organization, but no evidence of such a relationship for other countries. A further conclusion is that measures which increase the price of coffee beans can be expected to have little effect on coffee sales.Coffee Demand, Dynamic Panel Data, International Coffee Organization

Regional Business Cycles in New Zealand: Do they exist? What might drive them?

We use National Bank of New Zealand Regional Economic Activity data, to identify and characterise classical business cycle turning points, for New Zealand’s 14 regions and aggregate New Zealand activity. Using Concordance statistic measures, logistic model and GMM estimation methods, meaningful regional business cycles have been identified and a number of significant associations established. All regions exhibit cyclical asymmetry for both durations and amplitudes, and synchronisations between aggregate NZ activity and each region are contemporaneous. The regional cycles rarely die of old age but are terminated by particular events. The regions most highly synchronised with the NZ activity cycle are Auckland, Canterbury, and Nelson-Marlborough; those least so are Gisborne and Southland. Noticeably strong co-movements are evident for certain regions. Geographical proximity matters, and unusually dry conditions can be associated with cyclical downturns in certain regions. There is no discernable evidence of association with net immigration movements, and no significant evidence of regional cycle movements being associated with real house price cycles. The agriculture-based nature of the New Zealand economy is highlighted by the strong influence of external economic shocks on rural economic performance. In particular, there is considerable evidence of certain regional cycles being associated with movements in New Zealand’s aggregate terms of trade, real prices of milksolids, real dairy land prices and total rural land prices.

New Zealand's Current Account Deficit: Analysis based on the Intertemporal Optimisation Approach

New Zealand's Current Account of the Balance of Payments has been persistently in deficit since the early 1970s and increased markedly during the late 1990s. Is this a cause for significant concern? This paper tackles this question by evaluating New Zealand's external solvency, the degree of optimality of the intertemporal consumption smoothing through its current account, and whether its international financial capital flows have been used in an optimal (consumption-smoothing) fashion. We carry out statistical tests in relation to external solvency. We also estimate a "benchmark" consumption-smoothing component for its current account based on an intertemporal optimisation model in order to carry out tests of the optimality of the size and volatility of the current account. We could not reject the hypotheses that New Zealand's current account was consistent with optimal smoothing, that the external solvency condition has been satisfied, and that there is "no excess volatility" in international financial capital flows.current account; intertemporal; consumption-smoothing; New Zealand

Stylised facts for New Zealand business cycles: A post-1987 perspective

Key features of NZ business cycles were established for the period 1966q4 to 1990q1 by Kim, Buckle and Hall (1994) (KBH), but the conduct of fiscal, monetary and labour market policy and the behaviour of New Zealand's economy have changed considerably since then. Our results for the period 1987q2 to 2010q4 show a reduction in volatility and a rise in persistence for both the real economy and for price and monetary variables. Government sector, open economy, monetary and labour market results differ from those advanced in KBH. Overall, we establish a more credible set of benchmark regularities, to help underpin the construction and use of contemporary NZ macroeconomic models

An unobserved components common cycle for Australasia? Implications for a common currency

We use unobserved components methodology to establish an Australasian common cycle, and assess the extent to which region-specific cycles of Australian States and New Zealand are additionally important. West Australian and New Zealand region-specific growth cycles have exhibited distinctively different features, relative to the common cycle. For every Australasian region, the region-specific cycle variance dominates that of the common cycle, in contrast to findings for U.S. BEA regions and prior work for Australian States. The distinctiveness of New Zealand’s output and employment cycles is consistent with New Zealand retaining the flexibility of a separate currency and monetary policy, for periods when significant region-specific shocks occur

Recessions and Recoveries in New Zealand’s Post-Second World War Business Cycles

We compute classical real GDP business cycles and growth cycles, contrast classical recessions with ‘technical’ recessions, and assess the sensitivity of our peaks and troughs to data revisions. Using this information we find that, on average, real GDP and employment cycles have had an 89% association. Other key findings are (i) New Zealand’s average pattern of recovery has differed from that for U.S. NBER cycles, but their most recent recession and recovery paths have been unusually similar; (ii) the strength of New Zealand's business cycle recoveries has been independent of the depth, duration, or severity of the preceding recession; and (iii) investment is an important component of expansions, and in the current cycle it has been residential investment and plant and equipment investment that have been unusually slow to recover their levels at prior business cycle peaks
