Dr. Biswas's comment on this article

Dr. Biswas has reviewed this Wikipedia page, and provided us with the following comments to improve its quality:


I think it would be better if the welfare consequences of imposing a tariff be discussed in some details. Imposition of tariffs has two effects, it increases the output of the import competing sector and brings about a terms of trade improvement. In the case all the markets are characterized by perfect competition, the first channel becomes a source of welfare loss while the second channel improves it. This is because the import competing sector produces a good in which the country concern does not have comparative advantage. On the other hand, improvement in terms of trade makes the price of the importable in the world market fall which is good for the country.

This discussion implies that a small country can have only an optimal tariff equal to zero as there are no terms of trade effect for it ( a small country cannot affect the prices in the world market). Any imposition of tariff would only increase the output of the import competing sector and cause welfare loss. Still, it can be used to protect the import competing sector. For a large country with some monopoly power in the world market, the optimal tariff is always positive. {Reference:World Trade and Payments: An Introduction, 10/E, Richard E. Caves, Jeffrey A. Frankel, Ronald W. Jones} In case markets are imperfectly competitive, increase in output of the import competing sector may not be potentially welfare reducing. This can happen when there are economies of scale in the production. Presence of scale economies implies that as tariffs increase the output of the import competing sector, average costs are reduced which in turn means lower prices for the consumers. (Note that when trade takes place due to imperfect competition, it is not necessarily comparative advantage that drives trade.) {Reference: Krugman, P.R. (1994), Rethinking International Trade, MIT Press, Cambridge.}

Gros (1987){See Gros, D. (1987), "A Note on the Optimal Tariff, Retaliation and the Welfare Loss from Tariff Wars in a Framework with Intra-industry Trade", Journal of International Economics, Volume-23} further argues that when there is strong love for variety amongst the consumers, a small country also enjoys some monopoly power in the world market due to the production of the unique varieties (if there are fixed costs in production no two producer would produce the same varieties) in a trading equilibrium. This means that optimal tariff for a small country may not be necessarily be zero.

Assessment comment

The comment(s) below were originally left at Talk:Tariff/Comments, and are posted here for posterity. Following several discussions in past years, these subpages are now deprecated. The comments may be irrelevant or outdated; if so, please feel free to remove this section.

The economic analysis seems unnecessarily partisan. Rather than starting off with the theories of "libertarian economists", it would be good to first explain the widely recognized effects of tariffs. It may be appropriate to include which groups of people think those effects are good or bad, but I think that should only come after the explanation.

Dr. Crowley's comment on this article

Dr. Crowley has reviewed this Wikipedia page, and provided us with the following comments to improve its quality:


I think the material in the section "customs duty" is likely incorrect. This section is confusing at best. I recommend removing it entirely.

For evasion of custums duties section: Here is a recent publication

"Outsourcing Tariff Evasion: A New Explanation for Entrepôt Trade," Raymond Fisman & Peter Moustakerski & Shang-jin Wei), 2008, The Review of Economics and Statistics, MIT Press, 90(3): 587-592.

The section Economic Analysis does not contain any references to the more realistic case of a country that faces an upward sloping export supply curve. This is the focus of much current research on the topic. See Broda, Christian, Nuno Limao and David E. Weinstein. 2008. "Optimal Tariffs and Market Power: The Evidence." American Economic Review, 98(5): 2032-65. DOI: 10.1257/aer.98.5.2032

The section "Tariffs within technology strategies" is confusing and partially wrong. It does not provide enough concrete analysis to explain that rationale for infant industry tariffs nor does it precisely explain why they are often viewed with skepticism.

Tariff: Customs Duty vs Price Schedule

Tariff in many other languages refers to price schedules, while in English it primarily refers to customs duty, and it appears that lot of non-English wikis are pointing to the English Tariff wikipedia page as a false cognate (i.e. they are interpreting the English tariff page as being about price schedules). The current situation is that the primary English page, tariff, is associated with wikidata entry Q736288 - tariff (price paid or charged for a service), but given its English meaning and current content, it seems more appropriate to associate tariff with Q52389 - customs duties. I'm not sure about the appropriate English wiki page to associate with Q736288 - tariff (price paid or charged for a service). There is a linked discussion at Wikipedia talk:WikiProject Disambiguation and Talk:Tariff_(disambiguation) --Furicorn (talk) 23:47, 14 August 2017 (UTC)[reply]

I've stumbled across this page and taken the liberty to make a few changes:
  1. Changed those wikidata entries so that the german, french and japanese lemmas and / or descriptions in Q736288 are about "fixed charges or prices", or "fixed contract conditions (incl. prices) offered by the seller", and in Q52389 about "customs duties", i.e. taxes levied on imported or exported goods. I've checked the english wiktionary entries on "tariff" and "Tarif" (the german cognate, to which the wikidata entry linked) and the german wiktionary on "Tarif"; also, Merriam-Webster on "tariff". However, I'm not sure how to document these changes directly on wikidata and notify authors who might have worked on the entries. Is there any good way to do this? I've barely ever seen talk page discussions on wikidata.
  2. Rewrote the second sentence in the lead and clarified that this is not the meaning of the lemma in this article. Just before saving changes, I thought we might just delete it entirely, because this meaning is already mentioned in the disambiguation page and that page is in turn linked on the top (I was going to add the disambiguation link more prominently, but found no good template). Then I reconsidered, but forgot to change back my edit summary; thus another subsequent empty edit. If anyone with history editing privileges stumbles across this, feel free to merge the edits, if you like and policy allows.
  3. I have not placed any english, german or french wikipedia links in Q736288. I've failed to find an article on this lemma on any of these wikis. The english disambiguation page only references pricing. Seems to me that no one found this topic important enough for its own article?
I'd be happy for any hints or improvements. :) Se'taan (talk) 11:55, 20 January 2018 (UTC)[reply]
