We survey the relevant literature on translation difficulty and automatic evaluation of machine translation (MT) quality and investigate whether source text’s translation difficulty features contain any information about MT quality. We analyse the 2017–2019 Conferences on Machine Translation (WMT) data of machine translation quality of English news...

Language matters, and it is an overwhelming stylized fact that language translation is an unavoidable part of global business. In this paper, we quantify the impact of translation difficulty reflected by the presence of multiple-meaning words in the original text. We focus on international patent applications because patent prosecution is nation-ba...

The patent system underpins the business model of some of the fastest‐growing companies. Used appropriately, it should support frontier technologies and nurture new firms. Used perniciously, it can stifle innovation and protect established technological behemoths. We analyze patent examination decisions at the American, European, Japanese, Korean,...

Does the presence of specialist technological expertise, diversity across industries and the intensity of competition among existing firms in a location affect the rate at which new firms are attracted to an agglomeration? We construct three measures of these explanators including a novel measure of competitive dynamics and estimate a region-indust...

This article describes a new database—TM‐Link—that contains 12 million trademark applications and registrations across six jurisdictions. A feature of the database is the identification of trademark equivalents (or families) within and across national trademark offices. Equivalent trademarks are two, or more, insignias for the same product applied...

In contrast with quotas and tariffs, it is theoretically ambiguous whether fewer (or ‘weaker’) rules over intellectual property rights will increase or decrease trade in patentable goods. The prevailing view is that anticipation of imitation reduces exporters' incentive to export goods to jurisdictions with ‘weak’ patent regimes. This empirical pap...

Evidence suggests that patents facilitate technology transactions but the reasons for the effect are unclear. Patents may assist trade in technology by either: (i) protecting buyers against the expropriation of the idea (the 'appropriation effect'); or (ii) increasing information sharing during the negotiation phase through publication of technical...

One of the principles enshrined in all international patent treaties is that equal treatment should be provided to inventors regardless of their nationality. Little is known about whether this “national treatment” principle is upheld in practice. We analyze whether patent examination outcomes at the European and Japanese patent offices vary systema...

This article investigates whether patients who used a mixture of private and public hospital care have higher total hospital utilization than those who exclusively used either public or private hospital care. Using Australian hospital administrative data of heart disease patients, we found that those who used a mixture of private and public care ha...

This paper investigates the link between innovation and export market participation using Australian small and medium enterprises (SMEs) data. The results show that export and innovation are positively linked. Depending on the industry and the type of innovation (process or product), innovation may lead to export and, to a lesser extent, export may...

Conditional on the decision to enter the market for immature technology, we test for the effects that trust – as proxied by the context in which the negotiating parties met – has on the likelihood that these negotiations are successful. Using a randomised dataset of 860 university-firm and firm-firm technology transactions, we find that the depth o...

Patents may assist trade in technology either by protecting buyers against the expropriation of the idea by third parties (the appropriation effect) or by enabling sellers to more frankly disclose the idea during the negotiation phase (the disclosure effect). We test for the presence of both these effects using quasi-experimental matching analysis...

This paper investigates the effects of competition on hospital quality using hospital administration data from the State of Victoria, Australia. Hospital quality is measured by 30-day mortality rates and 30-day unplanned readmission rates. Competition is measured by Herfindahl-Hirschman index and the numbers of competing public and private hospital...

This paper investigates the direction of causality between export market participation and innovation using firm level data from Australia. Using the propensity score matching approach, the paper asks whether: (i) exporting in the current period is positively correlated with the probability to innovate in the same or the next period, (ii) the relat...

This paper studies the link between competition and technical efficiency of public hospitals in the state of Victoria, Australia. It finds a positive relationship between efficiency and competition as measured by the Hirschman–Herfindahl Index (HHI) and a negative relationship when the number of competing private hospitals is used instead of HHI. I...

In this paper, we estimate the extent of misclassification in patent examination decisions between the European Patent Office (EPO) and the Japanese Patent Office (JPO), that is, applications that are incorrectly refused a patent or incorrectly granted a patent. Using a proxy for inventive step as the predictor of the correct decision, we find that...

Recent evidence indicates that the relationship between age and health care expenditure is not as straightforward as it appears. In fact, micro-level studies find that time to death, rather than ageing, is possibly the main driver of the escalating health care costs in developed countries. Unfortunately, the evidence at the macro level is less clea...

This paper investigates the effects of competition on hospital quality. It proposes to extend the Elzinga-Hogarty quantity flow approach of defining markets by first determining the trading cluster to which each hospital belongs and then delineating markets using patient flow information. After defining hospital markets and computing measures of co...

One component of the duration of pending patents - why applicants choose to delay the examination process - is modelled. We use a matched sample of 9597 patent applications to examine this issue. Controlling for differences between patent offices, we find evidence that applicants create investment uncertainty by delaying decisions to request patent...

The Australian government implemented a series of private health insurance (PHI) policy reforms between 1997 and 2000. As a result, the proportion of the population with PHI coverage increased by more than 35%. However, this study found significant evidence that the policy reform disproportionately favours high-income earners. In particular, the 30...

This study looks at the link between the patterns of trade-revealed comparative advantage and net inward foreign direct investment in five developed countries: the United Kingdom, the United States, Japan, France, and Italy. It thus extends earlier work by Maskus and Webster (1995) who analyzed two countries, the United Kingdom and South Korea. Des...

This paper proposes a method of deriving a quality indicator for hospitals using mortality outcome measures. The method aggregates any number of mortality outcomes into a single indicator via a two-stage procedure. In the first stage, mortality outcomes are risk-adjusted using a system of seemingly unrelated regression equations. These risk-adjuste...

Australian and New Zealand environmental economists have played a significant role in the development of concepts and their application across three fields within their subdiscipline: non-market valuation, institutional economics and bioeconomic modelling. These contributions have been spurred on by debates within and outside the discipline. Much o...

This paper proposes a method of deriving a hospital quality performance indicator using mortality outcome measures. The method aggregates any number of mortality outcome measures observed over several years into a single indicator. We begin with the supposition that there exists an abstract quality index which drives all observed mortality outcomes...

The Australian government introduced three major private health insurance policy initiatives in recent years. These are, in chronological order, (i) the Private Health Insurance Incentives Scheme (PHIIS), which imposes a tax levy on high-income earners who do not have private health insurance and provides a means-tested subsidy schedule for low-inc...

We use unpublished establishment level data of Australian manufacturing from 1993-94 and 1996-97 censuses to study how trade liberalisation affects productivity. More specifically, we use the variation in the extent of trade liberalisation across four digit ANZSIC manufacturing industries classification to identify the link between trade liberalisa...

This paper investigates the geographic agglomeration of establishments in the Australian manufacturing industries during the period of 1994{1997. We find that although the agglomeration of Australian manufacturing has doubled during the period, it is still not as agglomerated as those in other developed economies such as the United States, the Unit...

Increased transmission capacity and diminishing returns to scale in power production capacities have raised the opportunity cost of electricity in many countries. The resulting market changes have often been counteracted by policy, i.e. subsidized electricity prices to for instance energy intensive industries. Firm data, emphasizing cost heterogene...

One component of the duration of pending patents – why applicants choose to delay the examination process – is modelled. We use a matched sample of 9,597 patent applications. Controlling for differences between patent offices, we find evidence of strategic behaviour by applicants.

We use a vertical control model with a two-part tariff pricing and a leader-follower competition to investigate some conditions which may prevent the occurrence of parallel importing even when such activity is legally permitted and the effects of parallel importing on the incentive to invest in market development effort for an authorised distributo...

We study the link between plant turnover and productivity using Indonesian plant-level data for the period of 1990-95. First, we compare productivity differentials among incumbents, entrants, and exiting plants by constructing the Farrell technical efficiency index using data envelopment analysis. We test the significance of these differentials usi...

We investigate the relationship between productivity, size and age of large Australian firms employing more than 100 employees or holding assets in excess of $100 million. In addition, we also investigate the extent of productivity persistence among these firms by looking at transition matrices of productivity distribution and productivity-rank mob...

The Australian government implemented a series of new private health insurance policies between 1997 and 2000. As a result, the proportion of the population with private health insurance coverage increased by more than 35%. However, this paper finds significant evidence that the policy reform disproportionately favours high income earners. In parti...

The Australian government implemented a sequence of new policies during 1997-2000 and raised the take-up rate of private health insurance (PHI) by 35 per cent. Because they were implemented sequentially, their individual effectiveness is not quite clear. We isolate the effects of Lifetime Health Cover (LHC) introduced at the last stage of the seque...

This study investigated the hypothesis that socioeconomic differences in health status change can largely be explained by the higher prevalence of individual health-risk behaviors among those of lower socioeconomic position. Data were from the Americans' Changing Lives study, a longitudinal survey of 3617 adults representative of the US non-institu...

In this paper, we estimate the number of misclassified patent applications at the EPO and JPO - that is, applications that are incorrectly refused a patent (Type I error) and applications that are incorrectly granted a patent (Type II error). Using a proxy for inventive step as the predictor of the correct decision, we estimate that 6.1 and 9.8 per...

This paper examines whether strategic trade behavior can explain the fact that the US, Japanese and European Patent Offices – the USPTO, the JPO and the EPO – often make different decisions about whether to grant (or reject) a given patent application. We analyse this issue by considering whether examination decisions across the patent offices va...
