The Impact of Traded Goods Prices on the New Zealand Economy*

Recent empirical work in Australia and New Zealand reveals a diversity of estimates of the dynamic response to changes in traded goods prices. Similarly, there is conflicting evidence as to whether relative purchasing power parity is a characteristic of models estimated from data. In this paper it is argued that a reduced form approach to empirical modelling is appropriate for New Zealand's particular circumstances. The resulting model is simulated in a novel way, with results that argue against the use of a simple traded/non-traded goods distinction in the analysis of foreign price impacts on New Zealand. Purchasing power parity is, however, consistent with the results.     

The Impact of Regret on Exports

We examine optimal production and export decisions of a firm facing exchange rate uncertainty, where the firm's management is not only risk averse but also regret averse, i.e., is characterized by a utility function that includes disutility from having chosen ex post suboptimal alternatives. Experimental and empirical results support the view that managers tend to be regret averse. Under regret aversion a negative risk premium need not preclude the firm from exporting which would be the case if the firm were only risk averse. Exporting creates an implicit hedge against the possibility of regret when the realized spot exchange rate turns out to be high. The regret‐averse firm as such has a greater ex ante incentive to export than the purely risk averse firm. Finally, we use a two‐state example to illustrate that the firm optimally exports more (less) to the foreign country than in the case of pure risk aversion if the low (high) spot exchange rate is more likely to prevail. Regret aversion as such plays a crucial role in determining the firm's optimal allocation between domestic sales and foreign exports.     

Passthrough of Exchange Rate and Tariffs into Import Prices of India: Currency Depreciation versus Import Liberalization*

This paper examines the extent of passthrough of exchange rate and tariff changes into import prices using sectoral panel data (at the two‐digit SITC level) for the post‐reform period in India (1990–2001). After having controlled for unobserved effects that might have an impact on the import prices by using sector dummies, we find that on average exchange rate passthrough (ERPT) is a dominant effect compared to tariff rate passthrough (TRPT) in explaining changes in India's import prices. The sectoral panel results suggest that the passthrough of exchange rates and tariff rates varies across products. ERPT into import prices is significant in 12 industries, whereas TRPT is significant only in six industries, with full passthrough. However, ERPT is incomplete only in four industries, but TRPT is incomplete in 36 industries, which means that firms exporting to India more frequently adopt strategies to maintain their market share against tariffs than against exchange rate changes. The sectoral differences in passthrough seem to be related to the sector's share in total imports and the sector's effective protection rate. Hence, India's relatively high levels of protection have an impact on the behavior of foreign exporters.     

Financial Market Imperfections and the Impact of Exchange Rate Movements on Exports*

This paper analyzes empirically the role of financial market imperfections in the way countries’ exports react to a currency depreciation. Using quarterly data for 27 developed and developing countries over the period 1990–2005, we find that the impact of a depreciation on exports will be less positive—or even negative—for a country if: (i) firms borrow in foreign currency; (ii) they are credit constrained; (iii) they are specialized in industries that require more external capital; (iv) the magnitude of depreciation or devaluation is large. This last result emphasizes the existence of a nonlinear relationship between an exchange rate depreciation and the reaction of a country's exports when financial imperfections are observed. This offers a new explanation for the consequences of recent currency crises in middle‐income countries.     

The Informational Role of Prices*

We consider a dominant firm with a competitive fringe in order to investigate the informational role of prices. The fringe is necessary for the existence of a unique, fully revealing equilibrium, in which the price reveals the quality of the good to uninformed buyers. A higher price triggers more sales on the part of the competitive fringe, reducing both residual demand and profits. We find that a larger share of uninformed buyers increases the price and reduces the quantity sold by the dominant firm, but increases the quantity sold by the competitive fringe. This, in turn, reduces consumer surplus and welfare.     

The Impact of Economic Sanctions on South African Exports

In the mid‐1980s many nations imposed sanctions on South African exports, most of which were subsequently removed during 1991–3. I estimate the effect of eight industrialized economies' sanctions on their imports from South Africa. Outliers are found to strongly influence the parameter estimates. Failure to take account of them leads to the conclusion that sanctions by the (then) European Communities most adversely affected South African exports. In fact, robustness checks reveal that the United States' Comprehensive Anti‐Apartheid Act played the largest role, reducing bilateral imports by a third. The broader implications of these findings for estimating gravity equations are discussed.     

人民币有效汇率对中国进出口贸易影响的研究

人民币在升值过程中伴随着贸易顺差增速过快的问题。人民币的升值虽能对进出口起到一定的促进作用,但不能从根本上解决贸易顺差的问题。解决贸易顺差问题的首要前提是要认清人民币升值的消极影响,其消极影响主要体现在对我国劳动密集型的出口企业造成冲击、影响外商投资积极性、增加企业对外经营合作风险三个方面。有针对性地消除人民币升值的消极影响,有助于解决贸易不平衡问题。具体需要政府引导企业转变贸易发展方式,合理选择和利用外资,同时,出口企业应结合金融工具与财务手段规避外汇结算风险。     

Pricing to Firm: an Analysis of Firm‐ and Product‐level Import Prices*

We use Hungarian Customs data on product‐level imports of manufacturing firms to document that the import price of a particular product varies substantially across buying firms. We relate the level of import prices to firm characteristics such as size, foreign ownership, and market power. We develop a theory of “pricing to firm” (PTF), where markups depend on the technology and competitive environment of the buyer. The predictions of the model are confirmed by the data: import prices are higher for firms with greater market power, and for more essential intermediate inputs (with a high share in material costs). We take account of the endogeneity of the buyer’s market power with respect to higher import prices and unobserved cost heterogeneity within product categories. The magnitude of PTF is big: the standard deviation of price predicted by PTF is 21.5%.     

Effects of Multilateral Trade Liberalization on Prices*

To analyze the effects of simultaneous tariff reductions by multiple importing countries on prices, we construct a simple three‐country model where a good is produced by a monopolist with nonconstant marginal cost and imported by two countries. We compare two representative tariff‐reduction formulas: the “fixed‐amount” and the “uniform percentage” reductions. The uniform percentage reductions may increase the consumer price in the importing country, whose initial tariff is lower. Thus, importing countries with relatively low tariffs may prefer a bilateral trade agreement to a multilateral one to ensure consumer gains.     

Sizing Up the Impact of Embassies on Exports

The purpose of this study is to test for the effects of trade promotion via the foreign service. The theory of trade with heterogeneous firms predicts that unilateral trade promotion allows medium‐sized firms to export. We investigate the effects of trade promotion using firm‐level data and information on the opening and closing of embassies abroad from the very similar neighboring countries Sweden and Norway. We use a difference‐in‐difference specification where firms from Norway are used as a control group for Swedish firms. Our results show that large firms as well as medium‐sized firms respond to the opening of embassies.     

The Impact of Exchange Rate Volatility on UK Exports to EU Countries

This paper investigates the impact of exchange rate volatility on UK exports to European Union (EU) countries by means of a newly developed ARDL bounds testing procedure to cointegration. Using monthly data disaggregated by market of destination and sectors for the period 1993ml to 2001m6, our results indicate that UK exports to the EU14, at both aggregate and sectoral level, are generally income elastic, relative price inelastic and largely unaffected by short‐term exchange rate volatility. Re‐estimation of the model using a long‐term measure of volatility, however, provides evidence supporting the hypothesis that exchange rate uncertainty has a negative and significant influence on UK exports to EU countries.

The Setting of Retail Prices in a Customer Market*

This paper extends the theory of the determination of retail prices in a customer market to a shop selling many types of goods. For a multi-good shop, a discontinuous marginal revenue function for each good sold is derived. Under reasonable assumptions the size of this discontinuity depends only on the customer dynamics and is independent of own-price elasticities and cross-price elasticities. A discussion of the determination of producer prices shows how the theory can explain the relative stability of retail prices.     

Prices vs. Quantities: The Irrelevance of Irreversibility*

We explore the efficacy of price and quantity controls in a dynamic setup in which the decisions of some agents are irreversible. The assumption of irreversibility is shown to improve the performance of a tax relative to that of a system of tradable quotas and significantly alter the equilibrium behavior of agents. We nevertheless conclude that taking into account the fact that agents’ decisions may be irreversible does not lead to policy implications significantly different from those reached in a simpler model in which irreversibility is ignored.     

Some Evidence on the Adjustment of Producer Prices*

We document producer price adjustment using a low‐inflation micro price dataset. On average 24% of prices adjust each month, with an average increase/decrease of 6%. Producer prices adjust more frequently than consumer prices, but their size of adjustment is typically smaller. Sectoral heterogeneity in the frequency of price adjustment is strongly related to heterogeneity in the cost structure. Fluctuations in aggregate producer price inflation occur to a large extent through variation in the relative share of upward and downward price adjustment.     

The Impact of a Disorderly Resolution of Global Imbalances on Global Wealth

Partly reflecting structural advantages such as liquidity and strong investor protection, foreigners have built up extremely large positions in US (as well as other dollar‐denominated) financial assets. This paper describes the impact on global wealth of an unanticipated shock to US financial markets. For every 10 per cent decline in the dollar, US equity markets, and US bond markets, total wealth losses to foreigners could amount to about 5 percentage points of foreign GDP. Four stylized facts emerge: (i) foreign countries, particularly emerging markets, are more exposed to US bonds than to US equities; (ii) over time US exposure has increased for most countries; (iii) on average, US asset holdings of developed countries and emerging markets (scaled by GDP) are very similar; and (iv) based on their reserves position alone, wealth losses of emerging market governments could on average amount to about 2¾ percentage points of their GDP.     

Impact Fees and Real Estate Prices: Evidence from 35 Chinese Cities

Local governments often charge developers impact fees to finance local public goods. This has been practiced in Chinese cities for more than two decades; however, no empirical studies have tested the effect of impact fees on real estate prices. Using a panel data set for 35 large- and medium-sized cities from 1998 to 2008, we find that impact fees lead to a significant increase in real estate prices. For a given city, an increase in impact fees by one yuan leads to an increase of about 5 yuan in the price of newly-built housing; a 1% increase in impact fees leads to an increase of 5 percentage points in the housing price index and 7 percentage points in the land price index.     

The Impact of Social Comparisons on Reciprocity*

In this paper, we investigate how social comparison information about referent others (i.e., learning what similar others do, and how they are treated) affects reciprocal relationships. Using three‐person gift‐exchange games, we study how employees’ reciprocity towards an employer is affected by pay comparison information (what co‐workers earn) and effort comparison information (how co‐workers perform). We find strong evidence of the effects of effort comparison: employees are more willing to reciprocate by choosing high effort in response to a high wage if they observe others doing so. In our setting, we find somewhat weaker evidence of the effects of pay comparison.
